Training Status on Maintaining for 5 weeks

Hi, when i got mu Fenix 7x solar in March the training status would vary.  But now its been stuck on Maintaining for 5 weeks.  My training is varied (im doing the 80/20 half marathon plan plus Crossfit) but no change at all.  This feels like a bug.  Is there anything i can do? Load is also optimal all the time.  

  • Are you doing different running workouts which are classified differently by your watch?
    Do you have external HR sensor?
    How your HR zones were set?

  • The workouts are usually tempo, vo2 max or threshold.  Even on vo2 max classified workouts my vo2 max shows and sideways arrow which i assume indicates staying the same.  Yes i have a HRM Pro Plus.  I don’t remember how my zones were set initially but i *think* i used the zones id set in Training Peaks based on the 80/20 tests I did when i started the plan. But i have accepted new values whenever the Fenix suggests them.
