Weapon Finesse not applying correctly

[KittyFangs]

I have a character that is dual wielding the Elven Thinblade, and Elven Lightblade. Weapon finesse has never applied to these properly. I can add a rapier to my character and the attach bonus is accurate, however, adding a short sword offhand pulls my STR modifier. For my elven weapons above, it has never applied Dex to the attack calculations at all. I have checked the data files and the weapons are properly marked Helper.finesse and the lightblade is also a light weapon anyways. Something weird is going on here. Please help!

I have attached the portfolio. There is one edit to my data files, as my DM allowed me to take Heroics as a bard. Otherwise, no edits have been made. I am using the community D20 dataset
