Config page resets with every new group type

[rosiel]

Every time I create a new group type, the bottom part of the Access Control with Groups page gets reset to "Select" (i.e. the media and nodes reset to not having any field selected. in fact i can't even select a field until every single group type has a taxonomy vocabulary associated with it.

This is a strange UI feature and probably should be more user-friendly and remember previously selected values.
