Greetings!

Ever since upgrading from ServiceDesk Plus 11 to 14 (currently on 14.2 Build 14200) a few months ago, we can no longer change/convert service requests to any other template after they've been closed. The Template drop-down menu is simply greyed out and cannot be interacted with while editing the service request:

This applies to all service request templates regardless of their status, even the default which we haven't modified in any way. Once Status has been changed to Closed and saved, there is no way to do anything about the template anymore. We've gone through our Admin settings, Googled, searched here on PitStop and in ServiceDesk Plus release notes from the past few years, but couldn't find anything. Is this even a bug, or some kind of intentional feature?

The problem does not affect incident requests at all, they can still be changed/converted in all cases.

Context:

We're currently performing a cleanup project in our ServiceDesk Plus instance, and trying to purge (not just disable) as many old junk templates / tasks / additional fields / etc as possible. Since templates (and other things) retain database relationships to any requests that ever used them, this means we have to go back and manually convert these requests to current templates, before the affected templates can be deleted. Highly time-consuming and not very glamorous, bulk template operations would be a nice feature.

The easy approach would simply be to delete all offending requests, but we cannot do that due to data retention policies. We would also like to avoid messing directly with the database, due to the risk of creating new problems.
