I am randomly more often finding when I forward annotate to UB that the analog and digital grounds do not connect. In additon some multisection IC power pin connections fail to be connected in UB.
Connect digital ground to analog ground is checked in my MS properties.
Is there any reason for this?

Turns out ot occur consistently when I have certain pages of my MS schematic active on top when I do the FA. Works fine if I don't have any of those certain pages active on top when I do the FA. This is a 7 page schematic. Three pages cannot be on top when I do the transfer, or the grounds do not connect. Bug has been submitted to NI.

Problem is still there in 12.0.653 as well.
The work around of exporting from page 1 of the schematic does not work either. This is in a flat 3 page design with no heirarchy.
How do I get my analog and digital grounds to connect now?

I did some testing with a small circuit and it seems to merge the grounds when I use the option in the Sheet Properties PCB Tab. Take a look at the attached screen shots.
In Ultiboard, it is possible to add a net bridge by going to Place -> Net Bridge. Then you can select both the nets (0 and GND) and merge them.
Hope this helps.

Tien Pham offered this solution which worked:
I saw the ground issue in the file you sent and you can fix it by replacing the digital ground with the one from V12. On the Spreadsheet View, click on the "Components" tab, select all the Dgnd symbols, next click the replace icon on the Spreadsheet to replace all symbols at the same time.
