Hi. Carl, I installed from scratch to my external drive then ran BiaB and from the dock just select Options / Keep in dock and all was well.

I had the same problem with some styles showing as N/A. As far as I remember I had to rebuild 3 or 4 times before they settled down. I'm not 100% certain but I think I installed the updates after rebuilding.
