Upper ribbon no longer has the Custom group

Greetings,

We have a custom addin that adds a pulldown at the top of Solidworks. We have recently moved from SW 2013 SP02 to SW 2015 SP02 and the pulldown is gone. The tabbed ribbon with the commands still is created, but no pulldown at the top.

Is there anything I should look for in the upgrade that I should change in my code that creates and installs the addin?

Thanks in advance for your time and attention,

Danny Bradford
