Your diagnostics has 2 files in the shares folder anonymized as l--s
Due to DOS/Windows naming conventions, where upper/lower case isn't significant, one of these has (1) appended so they won't have the same filename.
One of these has settings for a share that doesn't actually exist. The other share does exist but doesn't have any settings.
This is often caused by a user accidentally creating a share by specifying the wrong upper/lower case in a docker mapping or other path. Linux is case sensitive. Any folder at the top level of cache or array is automatically a user share, even if you didn't create it as a user share in the webUI.
I don't know what that share is named since it is anonymized, but you need to clean that up, since the cfg file that exists in config/shares on your flash drive doesn't actually correspond to the share due to the upper/lower case problem, and the actual share itself has no corresponding .cfg file, which means it has default settings. The default Use cache setting is No.
