Strange Trainer Glitch

[Starfoth The Burgundy Silk Rug]

For some strange reason, whenever I talk to Niruin to get archery training and select the dialogue option to be trained, he stands there with his mouth open moving his arms and there's no dialogue. It then returns to the first dialogue menu.
I'm level thirty-something in archery and this glitch is incredibly annoying. Does anyone have a fix?

First question is usually mods? Assuming you checked the wiki for known bugs/work-arounds.

Mostly graphical or minor tweaks.
Minor tweaks meaning food buffer, 90% pickpocketing hardcap removal, graphical mods such as water or textures, and some random buildings added here and there.

I hate to be a thread necromancer, but has anyone found a fix for this? I've had the same issue both in the original and SE, with or without mods. In the original, I had the problem as described by the OP, but in SE, the dialogue works properly, yet it seems to think I've already been trained to the max by him (5/5) even though it was the first time speaking to him. This, also, was after making the skill legendary, but that shouldn't make a difference since it drops the skill back to 15, yes?
