Shrinking violet in 1st Person

[Bluegunk]

Does anyone know why my Dovahkiin very slowly reduces in height in 1st person?

I keep adjusting the 1st person camera in Racemenu (using the Vanity Mirror Mod) and adjust her from time to time.

After a few days, she's looking up at every one again.

At this rate I'll run out of the positive side of the slider around about the time she meets Paarthanux.

 

I use a mods like Customible Camera, Alternate Conversation Camera.

 

Is there an easy fix to this, please?
