Watch Face Problems

I have been using the GearMin Watch face for a while now on my Fenix 5 x. And only found out today is you calibrate the altimeter via GPS and reload the Watch Face this corrects the Sunrise Sunset N/a.
All was fine for a couple of hours then i noticed watch face had changed back to standard Fenix 5 watch face when i try loading the GearMin watch face now it just shows up as IQ with the excalmation mark.
How has this happened with no updates applied to watch?
