Strange Behaviour assigning a USB to Keepass

I use KeepassXC a whole lot on my Qubes lappy, and each time I assign the USB that contains my keyfile to Vault in order to use it on Keepass, the USB will not appear as a Device when I browse for it.

The stranger thing is it WILL appear when I navigate to /media/device/ ONLY after I open Vault’s File Manager. If I don’t open Vault’s File Manager beforehand, the USB does not show itself when I browse through Keepass.

Any idea on what the issue is here? Is this a Keepass issue on Qubes or a Qubes issue with Keepass?
