Collaboration on Transaction Group

We have noticed that when two people are working in the same project updating transaction groups that the changes do not show for each other until they close and reopen the designer. After clicking save and having the other designer click the merge any new changes button none of the changes appear.

Any ideas on how to collaborate in a sqlbridge transaction group project without overwriting other designer changes?

Thank you,

Jonathan, this seems like a bug. I am able to replicate the behavior and will be filing an internal ticket to have it fixed.
On a side note, you should not be able to have both users look at the same transaction group at the same time at all.
