Vocabulary don't appear in the same order in the nodes groups.

The display of the vocabs depended on the time the terms were tagged to the node. Steps to reproduce:
1. Create a group, group content and two vocabularies related to the group content type(i checked this on a auto complete form type)
2. Create node(AKA "Node a") and tag term from vocab A
3. Create node(AKA "Node b") and tag term from vocab B
4. Tag term from vocab B to node a
5. Tag term from vocab A to node b

You can see that the vocab don't appear in the same order.
