Firefox extension displaying otp codes for logins that don't use it

I'm in Firefox and using extension v2.2.1 on Windows. I noticed otp codes showing up in some logins in the toolbar window that don't use otp. If I switch the display filter in the upper left to Logins and start clicking through the items, the otp code shows up for a bunch of items in the list after one of the logins that legitimately does have a code. In fact the code itself is all from that one login, it's just also being shown for a bunch of additional items past it. This has got to be a bug.
