Which sounds did you find on there? Link it to me. All of these were made by me and my 5th update was made with my brother in law who also makes sounds. Potentially those are some of his. I'll remedy any discrepancy.
Edit: Just for reference as well, all of the sounds I made with my BIL have his metadata associated with them. He makes some great free music so check him out if you're interested :)
