I told you the three "sources" of collision issues in my first post. If you want to fix this yourself, you can start here.
But what I was refering to above, was the fact that, if you encounter a problem with a specific model, you might want to ask the creator of that appearance. If some of your things are patreon/ko-fi and so on, you actually paid for content, which obviously allows you to ask for support (at least a tiny bit) for it. And here on the hub, there's a release discussion, so dropping in that discussion a couple of question is always ideal as you're asking the person who created it.
