Just so I understand and test this correctly. I have two groups with different fixtures in them, I then select the first group and merge it into the second group and then a dup group is appearing?
Yes, I was seeing the same thing. 2.5.0. But I thought it was with the same types of fixtures, not different. For instance Group 1, Fixtures 1-10 Group 2, Fixture 1-6 Group 3, Fixtures 7-12
Select group 2 + 3, Merge Group 1. Creates a dup group on row below.
Using Record instead of Merge seems to work. I see the dup when using Merge. Try selecting GROUP 1 + GROUP 2 RECORD GROUP 3 MERGE, when the option appears. The + sign appears to be optional.
