Dragonborn Talvas Fathryon Bug

[Nichoice]

For whatever reason, Talvas Fathryon's follower dialogue is bugged.

 

After completing the quest in which I destroy the ash spawn he summoned, I get the follow me dialogue.

 

However there is two follow me dialogue options and if I dismiss him, though EFF registers him as left me there is no follow me dialogue and the dialogue from EFF remains i.e. Command, I want to trade with you etc.

 

I have a few ideas, it could just be EFF using dialogue commands thats bugged, could be some wild edit in some mod.

 

This though is a minor issue, but I was wondering if anyone has had this occur.
