Ableton doesn't let me delete unused files

Hi
I'm actually tidying up / cleaning up my ableton projects and sets, and I'm experiencing a very frustrating issue :

When I go to "manage files" in one of my set I see that I've a bunch of "unused files", so I click on "Show" so all those unused files get listed in the left pane, but when I right click on those files, Ableton doesn't let me delete them (delete option isn't even shown inside the contextual menu).

I'm ABSOLUTLY SURE that those unused files aren't used by any other Ableton Live Set. They're only dependant to this specific Live Set, and only this one.
That's why I'm kind of surprised that Ableton doesn't let me delete them... Yes, I can go the good old Win Explorer hard way and delete them one by one, but damn, that's hundreds of files...

Does anyone has ever experienced this issue, and possibly found clues about it ?

Usually that's because of the backed up .als saved in the Backup folder in the project.

I've already deleted all backup sets from Windows Explorer, I don't get how it could be related to them

If you save the project to a new location, then do collect all and save, are the files you want to delete still there in the project folder? Can you delete them then?

I have the same problem and I wonder why they put useless stuff in new version instead of making the workflow straight...

Any tech support info on this? please, thanks

yes they get back even if they're not anymore present in arrangement!
