You see, you used the cursed warehouse functionality:
When i removed the warehouse file from your mission, it began to work:
DO NOT USE THE WAREHOUSE FUNCTIONALITY.
It doesnt work. It never worked. Avoid it entirely.
Whenever you use it in a mission, that mission file becomes incompatible with DCS after an update (or rather, after every time ED adds a new weapon to DCS). It breaks then, as you can see in the first screen shot with the empty lines in the table.
