You are using the #Db# tag in the opacity field. If you set your watch to 24h then the value a 4 o’clock in the afternoon is 16 and not 4. So it will not show.
So for the opacity value, change the formulas to use #Dh#, then it does not matter what you set you watch to.
Example fo Uur4:
- OLD:
$#Db#=4?100:0$ - Better:
$#Dh#=4?100:0$
