'proton vpn' not found

I run Proton VPN on all my devices and I have a record in 1P titled 'Proton VPN'. Just now, on my Samsung tablet, running Android 12, I needed to log in to Proton VPN. When I got to the password field there was a prompt to connect to 1 Password. "Great!", I thought. When I tapped on the prompt I was informed that 1P has no record for "proton vpn".  As noted above, it has such a record, although it uses upper/lower case, i.e, "Proton VPN". I can't believe that 1P is confused by upper/lower case differences, or is it?
