I don't see any option to select a custom status in advanced search now on this version. Very nice that it allows complete state but not the individual statuses are gone. Anyone managed to fix this.
v1.11.0-rc1 Advanced Search No Option for Custom Statuses
So having looking into this a bit more my question now is how do i can TicketStatus / StatusName to appear in this list below TicketStatus / State. I see that in the advanced search in this version StatusName has now been replaced by State.
Sorry I do not run beta software on my production sites so I cannot confirm this issue.
If this issue can be replicated on a fresh install I would recommend that you report the issue at github.
