Time spend with Warframes in the plains is not taken into account

[(PSN)Silenceform]

I've been doing the bounties with my Saryn Prime when the Prime Vault was open since mid November easily for more than 70 hours of time played and i still get the same amount of percentage with her in my equipment screen of my profile when my weapons i've been used with her over the same period of time have their percentage increased.

This bug makes statistics of my Warframes from my profile when classed by " Most used " inaccurate.
