CONSOLE branch mode problem

Hello

It's about 2 months that I have the V-700 console. I have been facing several bugs and inefficiencies but the most annoying one is this:

In branch mode I can not insert the send for all the tracks. Depending on the number of the tracks, some times I can just insert send from track 1 to 10 and sometimes to track 12 and the other time to track 18. Sends can't be inserted in the rest of the tracks(branch mode starts to misbehave).

My OS is windows 7 64bit ultimate edition.
Sonar 8.5

Has anybody encountered the same issue?

Best wishes
