So, bad news regarding feats. I lowered Valerie's character level using the the Cheat Engine table and then edit the save file to decrease her class level from 2 to 1, as discussed here:
viewtopic.php?f=2&t=7954, and it worked. Valerie had decreased from character level 2 and class level 2 to character level 1 and class level 1, and I was able to level her up again. Unfortunately, upon leveling her up to level 2 again. I was unable to choose an additional feat. Since the Fighter's level 2 combat feat had already been chosen, the game did not allow me to choose the same Fighter level 2 feat again.
As you can see, at the beginning of Level 2 level up process the new Feat slot had already been filled with the Shield Focus, that I had chosen during Valerie's first time leveling to Level 2. It seems that feats are basically slot based. Instead of having a heading called Feats, and under that are all feats placed, it seems that feats are managed as slots being filled. So for Fighters there are slots called Fighter Level 2 Feat, and so on, and that slot can only be filled once.
