P3D v4 AI ships visibility on ATC system

I'm finding that AI ships I have positioned are always visible to the eye but not always seen on the ATC system. They tend to be seen for short periods then disappear. It is almost like they always have scenery characteristics but that their AI appearance/existence is temporary, intermittent and unpredictable.
Any clues why?

Sort of. I’m noticing that the ship altitude can go negative. I suppose that would mean it is not traffic on the ground nor traffic in the air so that drops it off the ATC System. I’ll look at placing it on the ground somewhere. Other ships that hold a steady positive altitude appear for longer periods, but they also disappear for periods of time. I do think it is down to where the reference position is.

Just to close this out, Bob McElrath found that using a traffic filter of 59 which is “ALL” solved the issue.
