I have problems with this: I'm trying to search issues that do not have a fixversion. I hid the fixversion in the field configuration for a project, but when I create a new issue, the issue does not appear in the filter. I don'n know why this doesn't work if the filter is "fixversion is empty", and I suppose if I don't set any fixversion for a issue this value is empty.
I need this because I want the only one fixversion in my issues be the realease fixversion from de kanban board.
So, what can I do?
