Sometime, in new group/category pop-up, the group type is visible with category selected
On rare case, I saw the "create a new item" of the group page mis behaving for the [group|category] switch: the line "group type: [x static][o dynamic]" is still visible, even when [category] is chosen.
It seems to be related to the sequence of group and category creation, move, deletion, update (especilly update of category). But I wasn't able to find a reliable reproduction scenario.
I saw it on Chrome.
