The experience points of the Warframes in my profile stopped rising. help

[jiho04]

My profile XP on Mesa Prime and Saryn Saryn Prime hasn't increased any more for a year or two.

Mesa is 66 million experience, Saryn is 61 million experience.
It's a Warframe I use often, but I'm upset that the experience doesn't go up.
Please check and correct.

I believe if you forma the equipment it starts tracking over from 0, so you'd have to reach above 66 million for it to update. I'm not sure if that's intended or not but from what I've read it's been like that for years.
