Problem with my profile.

I've got a problem with some gear in my profile after applying a forma on any gear some of them stopped to get experience.

Your Weapon/Warframe gets set back to lvl 0 but keeps some points according to your mastery rank.

Lets say your Mastery rank is 10 and you forma a weapon. Its level will be 0 but keeps 10 Points which you can freely use right from the start.
If it has an Catalyst the points will be doubled. In this case 20.

BUT: It will gain no extra points until it reaches a higher level as your mastery rank. In this case 10. So till level 10, it gains no extra points, with level 11 it will get 1 (or 2 with catalyst) point(s).

Same is true for new gear without putting a forma into it.

 

But if you really mean experience, which means your weapons arent leveling at all: Which frame + abilities are you using?
For example, using an Excaliburs Exalted Blade wont give you any exp to your melee weapon. Same is true for every other "Abilityweapon" (Ivara's bow, Valkyrs Hysteria)
