Error when changing mask parameter in-line

I'm running a big simulation with lots of mask and parameter that i can change during simulation. But with one particular mask whenever i try to change parameter i'm getting this error : "Mask variable 'A' of 'NameBlock' was not changed by the mask initialization commands at the time of compilation but it is being changed by the mask initialization commands now. This is not allowed when in-lined parameters is on."

I've tried changing the block or using another working one, but it didn't solve it. ALl others mask work well.

Any idea what is the problem?
