About the "shared multimedia" and "multimedia" folders

[eauchat]

Describe the bug

In some server, I have no use for the "Shared multimedia" folder, which is confusing to some users (they put some private pictures in it without understanding that everyone who has an account on the server will see them). Looking into how to deactivate that folder, I imagined that the "External storage" is probably what mounts those folders. But opening that setting, I get the following screenshot:

I guess there is (or was) a bug in the nextcloud package that recreated multiple time the external storages. I imagine that if I remove all duplicates nothing should happen, and it will look cleaner. Does that make sense?

If I remove all "Shared multimedia" external storage, I imagine that it will stop showing the "Shared multimedia" folder. Is this the appropriate way to achieve what I was mentioning in the first paragraph?
