line "-- stop queue here --" disapeared when set enable per-set queues

@brzGatsu can you have a look please, I guess you implemented the PR?

When enabling the feature you need to redo your queues for every set, so the -stop queue- entry usually moves to the bottom of the list - did you scroll all the way to the bottom and check the entire list? I cannot reproduce the issue.

I think I found it!
First Reset Everything
Uncheck Allow empty slots
Go to Queue tab and check any slot
