When trying to mark a ticket from "Fixed" to one of these values:
..and perhaps also other values, I get a message like that:
Unknown field [Fixed in build] of type [Issue]. Workflow rule "jetbrains-youtrack-updateFixBuild->Clear Fixed in build on issue unresolve" thrown exception in project xxxxxxxx. Contact rule owner root (root) for futher information.
I'm not sure if this is a bug or something I did wrong in the administration area.
If is the second case, how can I restore YouTrack settings, without losing my existing data?
