[weird dots generated with tree support in CURA 3.2.1]

By seam do you mean holes on the surface / incomplete surfaces? I'll check the model again

[weird dots generated with tree support in CURA 3.2.1]

Hello everyone! My first post here and I have a question about tree support in CURA 3.2.1.

 

After turning on the tree supports, some weird dots generates around layer 63 in the air. I tried unchecking the 'Show Helpers' box to make sure they are not coming from the model.

I have attached a few photos for reference. Anyone knows what is the problem here and how to fix it? Thanks!!
