This bug still persists in Version 2024.002.20759.
There are reports about this bug in the forums dating back to at least 2018. One would think that within six years Adobe should have fixed such a clear incompatibility with the official, built-in way that file management works on macOS and iOS, i.e. two major platforms that Adobe Acrobat is built for.
Looking deeper into this, it seems that upon saving a file in which an annotation has been removed, the xattr (i.e., extended attribute) com.apple.metadata:_kMDItemUserTags is entirely gone from the file. So somehow, Acrobat seems to corrupt the metadata of the file in the filesystem.
