Arsenal does not show the correct stats. From displaying wrong health when changing mods, to not displaying correct ability stats.

I had it display wrong health stats across multiple mod changes and warframes yesterday however I do not have screenshots of it
I went to simulacrum, back to orbiter, changed mods and the stat was broken
