[otrs] Lost access to status "removed" after ITSM upgrade

Since installing the ITSM upgrade (OTRS 2.3.4 + ITSM 1.2.3), I can no longer set tickets to the "removed" status. I have checked in Admin-

Statuses and it's still there, but I'm not sure whether there is some new relationship mapping that now prevents me from choosing it.

When I close a call, I get the following choices: "Close Successful", "Closed Unsuccessful" and "Closed With Workaround". I have previously configured notes to allow status change, but when I add a note, the only available statuses are the above, plus "open", "pending auto close +", "pending auto close -" and "pending reminder". What have I missed? Regards, Richard Cross.
