~SETUP-BDTOBV16.TP2~ #0 #0 // MULTI-STRONGHOLD. All the warrior classes (fighters, rangers and paladins) and monks may get the De’Arnise Keep as their stronghold in addition to another stronghold which is accessible according to their class. Also all dual- and multi-classes have no restrictions to the number of strongholds they may obtain.
~SETUP-BDTOBV16.TP2~ #0 #1 // GRAND MASTERY FIX. This fix originally created by James Schumacher you may get from various sources including Baldurdash tweaks and cheats. It fixes the weapon proficiency table for fighters according to the original D&D rules implemented in BG1 and IWD. If you have not installed it yet I would strongly recommend to do so.

With this info, I think it is a Baldurdash v1.6.4 issue or lack of.
