Sorry for the late response, I was gathering some of those bugs that I found that are related to showing different information from what it is supposed to display on the Menu so here it goes: (Note: this findings where found on when I played on Windows with version of the game 1.3.8)
The first one is that when you apply "Power of Piercing" 
on Damon you will get 5 stack of Pierce Energy, but you will not get 1 Fear of Striking. This is the before:
and this is the after:
The second one that I found is that if you apply "Knowledge" to your party (doesn't matter what members do you have) it says that it should grant you "Max MP +15"
but instead it actually grants you "Max MP +10" on the Menu.
The third thing that I noticed is that if you apply "Extra Life" it states "Recovers 25% HP when incapacitated"
but on the Menu it says that it actually grants you 35% HP.
The fourth thing that I noticed is that if you apply "Power of Striking"
on Wulfric it will never be granted on him, and instead it will be granted on your Slime companion. At first I thought that maybe I misclicked, so here it was the first attempt before and after:
Here it was the second attempt before and after:
And here it was the third attempt before and after:
The fifth thing that I noticed is that if use "Power of Piercing"
on Goro, it will grant you 5 stacks of Pierce Energy, but you will not get 1 Fear of Striking. Here is the before:
and here is the after:
Lastly, I notice that there was a mispelling of the word "Spiritual Force I" during a battle.
If you noticed I have just played two different parties, but if I found more issues in another parties I will let you know.
