Thracia 776 missing animations

[HaTr]

Hello, this is my first time posting. Please forgive me if I make a mistake or break a rule. English is not my primary language so I apologize if I don't make sense or if my grammar is bad.

 

I'll try to be as brief as possible. I want to know how to fix the missing animations from Thracia 776. I made Finn a Master Knight since that is a class that is not in the base game to see how finished it was and I noticed that the bow animation looked really glitch-y.  What I'm trying to make is a silly edit of Thracia 776 that lets me use stuff like Master Knight Leif with Meisterbogen like in Fire Emblem Heroes, and maybe other silly edits. I know it's a really dumb question. I tried looking for a fix and there was a link to something but the link was expired. I'm using Nightmare because it's the only thing I know of. Again I am really sorry for my question and I hope you have a happy holiday season!
