Unable to "Allow deleting" when sharing a folder in External Storage

I’ve added a Local external storage folder, which is only available to the user “root”. Using this folder as “root” works perfectly well.

I want to be able to share individual folders in my external storage folder. This works fine as well - except I’m unable to give other users permission to delete. I can allow editing, creating, and resharing of files, but the checkbox to “Allow delete” is disabled.

When sharing a folder not in external storage, I can “allow deleting” for the same users, no problem.

Any idea how I can configure external storage to allow for sharing the “Allow delete” permissions? This is my first time posting here, thank you very much for any help!
