Strange Error in AE

Hey everyone,

I just got a strange error in my current project, as you can see I have black lines that do not exist in my layers, I triple checked all my layers and everything I could, but couldn't find the root of this!

Any advise if this is a problem of AE or Element 3D?

Cheers.

Update * I just got another error, really strange, it's getting worse! Anyone knows what's going on?
