Exclusion Zones. Are they able to suppress scenery items? I am going to try Flatten Mask Exclude Autogen and see how that goes. Perhaps it is Orbx Trees on the Bendigo tiles. I will uninstall them if all else fails as experiment.

Let us remember that we must first create a FTX Central Scenery Library Insertion Point to leave room at the top for
our files:

FYI: I no longer maintain an installation of my OrbX scenery purchased via the FlightSim Store after they 'gutted' that entity.
However, IIRC from descriptions in Misc. FS forums, OrbX HD Trees are used as Autogen under their original FSX / P3D GUIDs, and have merely had a swap of texture sets.
If they use 'default' FS GUIDs, that 'may' mean they could be excluded by one of the options available in a Exclusion
Rectangle.
See: ADE version 1.65 Manual PDF file -

14.12.1 Creating an Exclusion Rectangle - Page 273 / 309
But, AFAIK, it may also merit testing via ADE to use a Exclusion
Polygon with an attribute of Exclude Autogen.
NOTE: A Exclusion
Polygon is not to be confused with a Exclude
Rectangle.

FYI: Airport Background / Boundary vector polygons can be assigned single attributes, referenced by their GUID:
{47d48287-3ade-4fc5-8bec-b6b36901e612} Flatten
{1f2baab1-4132-416e-8f6f-28abe79cd60b} MaskClassMap
{6c0c6528-5cf1-483a-a586-2c905cf2757e} ExcludeAutogen
...or combinations of- 2, or 3 attributes:
{5a7f944c-3d79-4e0c-82f5-04844e5dc653} Flatten + MaskClassMap
{18580a63-fc8f-4a02-a622-8a1e073e627b} Flatten + ExcludeAutogen
{594e70c8-06a5-4e3f-be6e-4dbf50b49d11} MaskClassMap + ExcludeAutogen
{46bfb3bd-ce68-418e-8112-feba17428ace} Flatten + MaskClassMap + ExcludeAutogen

Additionally, if by any chance the trees have been placed not as Autogen objects, but instead as scenery library objects, there may some additional considerations required to successfully exclude them ...as discussed here:
https://www.fsdeveloper.com/forum/threads/unable-to-delete-airport-library-objects.445748/
Also, if a layer of custom photo-real land class textures is annotated with trees:
https://www.avsim.com/files/oldlib/...&sig=35045a457ef86cd2a069832bcb907f89d5e29045
...and is located underneath FTX Global LC_NA, one may have "pop-through" trees showing up:
https://www.fsdeveloper.com/forum/threads/annotator-question-fsx.438054/
This thread deals with OrbX scenery Autogen in P3Dv3, but may still work:

BTW: For the same reason complexities and undocumented interactions of
that mix of add-ons would be your worst nightmare, a would-be helper may find supporting what you are trying to do, to also
be their worst nightmare.
Be aware OrbX may oppose attempts to modify scenery using- or 'placing'- any of their scenery objects via their GUIDs, thus AFAIK, you will not be allowed to publicly distribute, scenery you make which utilizes any aspect of the OrbX scenery assets / GUIDs.
If you are only making scenery for your own private purposes, that IMHO, is your own option to explore ...in private.
However, I consider it unlikely that you will see an abundance of support here for endeavors using that mix of scenery add-ons.
Not because it cannot be sorted out and done for private purposes, but because it is impractical and time-consuming to do so.
Perhaps you may see more folks here who are ready / willing / able to help with your endeavors after you begin using MSFS.
Good Luck with your endeavors.
