Hi John,
Can you post a picture of it? It would help determine what's going on. I'm also wondering about your scenery library order, but we can investigate that later. Take a screenshot and post it, so we can see what you are seeing, please. Thanks.
Also, take a look at Annette Island to see if trees are scattered there. Misty's Place is probably not the "best" place to check. It is totally created by RTMM, whereas PANT is a default FSX airport (with scenery added to it).
Open FTX Central and cycle regions. That is, choose a different region and then switch back. See if that fixes it.
