Quick Create Dialog on Rapid Board does change fields when changing issue type

To replicate:

Setup a blank instance, add a new project, GreenHopper and a new custom field, only add it to Epic type issues and add it to all screens.

Go to the rapid board, choose create and start with the issue type Bug, you won't see the field you just created. If you switch to Epic, it still won't appear. Vice versa if you start with Epic, that field will still appear even after switching back to Bug.

Tested against 5.8.7, but not an issue in GH 5.9, so upgrading to JIRA 5.0 + GH 5.9 fixes this issue.
