Ok, maybe a bit of a small list of things I am coming across.
This one is a bit irritating because we talked about it and you should implement the rules correctly. Your use of 'default' in weapons is incorrect. When characters buy weapon skills, they buy them in categories. Within each category, they pick a specific weapon to be the 'default'. All other weapons in the same category are at -10. This is clear under the rules for weapon skills. You are using it as a print option and not enforcing this rule at all. This must be fixed because it will give an incorrect OB for any non-default weapon.
The 'items' database is not populating for me. It is also not saving any item I manually enter.
On adding skill ranks for weapons, the OB is updating on the OB/DB tab, but the skill ranks are not.
It doesn't seem to be picking up my main gauche DB as shield.
Printing does seem to show PPs.
More to come.....
