MasterCautionSystem_FO Gauge is inactive

I am trying to add a new view with FO's MasterCaution
These are the lines in my panel.cfg:

[Window37]
Background_color=0,0,0
size_mm=47,23
window_size_ratio=1.000
position=0
visible=0
ident=10037
window_size= 0.100, 0.100
window_pos= 0.000, 0.000
gauge00=PMDG_737NGX!MasterCautionSystem_FO, -51,-5,100,42

The gauge appears as expected BUT is inoperative!
Not clickable and not lighting

When I try with PMDG_737NGX!MasterCautionSystem_Captain all is OK

Any ideas?
