Using Kali Linux 2024.2 (bare metal install).
The current issue did not use to be present, and was noticed just a couple weeks ago.

When right-clicking on a file, then selecting "Compress", to compress a file (or files) into a .zip file, you are also provided with a line where you can enter in what you want the output zip file to be named.
After entering in a name for the zip file, then continuing by pressing "compress", a new zip file is created, but the filename that was entered (to use for the new zip file) is NOT what the new zip file will be named.

I've noticed that when compressing a single file into a zip, the new zip file will be named whatever the single files name is, and will end in .zip.
When compressing multiple files, regardless of what you enter in for the new zip file to be named, once compressed, the new zip file will be given the name of whatever the folder/directory name is where the files being compressed are stored.

See attached screenshots for examples (with red highlighted areas to notice).
