Short description of error
I'm using an object with a mirror modifier as a boolean object to cut out bits from another object but the mirrored side of the boolean object does not cut anything.
Exact steps for others to reproduce the error
Please use the attached blend file to reproduce the problem.
There are 2 boolean modifiers. Each one is using an object that has a mirror modifier as well. With the one boolean modifier only one half of the mirrored objects is cutting and with the other boolean modifier nothing gets cut.
Another peculiar thing in this model: There is also a bevel modifier on the object. When I disable the bevel modifier in the viewport the boolean modifier is disabled as well.
Here is the blend file that shows the problem:
