FSX 2004 to fsx cockpit FX fail

Hello everyone. It is my first post and to start I will tell you about a small problem with a FS2004 plane that was adapted to FSX, the deHaviland Comet. The problem is simple: when drops of water fall on the windshield it turns blue. I remember that in FS2004 there was an FX of water droplets sliding down the windshield and I don't know if this has anything to do with it.
I have removed the FXs from the config file and the problem persists. Could you tell me what can I do? Thank you
