Can't adjust macro goals....keeps resting back to original settings!

I've used myfitnesspal for a year and in the last 2 months it won't set my goal weight, I assuming as comes under national bmi which isn't always correct way at to measure.....i compete am physically very healthy but probably would come on bmi....my partner states he's close obese again does body building has just 12% fat. This needs be changed. what now is really frustrating me updated new version every time macros resets back government guidelines. The weight can deal with was maintenance wanting right....i use app track macros.....but you've changed that well! if we can't our own please tell point of anyone who ifym or competing!.
