Can you send me a simple test project with your models showing this issue? I can take a better look at it that way. Layout debug may not help since you can't use the ACE. I send sendgb.com to share files temporarily.
Oh, got it! I've just sent a link to the project to the email address available on your website. I could not join the Discord community for some reason. I hope that is alright.
Okay, I think the main issue is that the 3D model object origins are in the corner. If you center the origin in the 3D model (e.g., in Blender, etc., and export again), you will likely need to reposition your models in the layout. Also, keep the bounding box a little larger.
