Issues with deleting structs

Hi all,

I tried deleting a few old structs that I don’t use but it appears that they aren’t truly deleted. I looked my project’s blueprints in windows explorer and can still see that the “deleted” struct files are still there with a size of 1kb. Additionally, I cannot rename any structs to have the same name as the “deleted” structs (which is how I found out about this issue, since the old structs were outdated versions of new structs I made). I guess this isn’t that big of a problem, but it bothers me to have the old files there. Is there any way to fix this and/or make it not happen? Thanks in advance.
