Sync: inconsistency in saving files you aren't authorized to edit

As the title says, I've stumbled upon a problem. People in my organization shared a CC folder with me, which I am only able to view (I'm not authorized to edit, delete or add files). However, if I open up a PSD in that folder and I accidentally hit "save" (without saving it anywhere else but the folder I am not allowed to make changes in), CC ends up trying to sync the file anyway, and it is currently doing this with every other sync that I do with my CC folder.  I've searched, but I did not find an option in CC to discard changes (or to put the file back into a previous version on assets.adobe.com, since the changes are -you've guessed it- not synced online).

So now I am currently in a loop that does not allow me to escape it. I can't overwrite a file online (as intended), but I can somehow submit changes on my local version of this CC folder, which CC will try to sync (which it can't do, as intended), which I can't undo anymore. This inability to undo it is a problem, or the fact that my sync gets stuck in a forever-incomplete state on a permission conflict is a problem.

I've read that I could sign out, rename/delete my Creative Cloud Files folder, but isn't that treating the symptoms rather than fighting the cause? Isn't there a better solution, or is this simply an oversight in the sync mechanism of Adobe CC?
