“Remove beneficial effects” does not work under missions tab. Zero credit.

[Tiñez]

I do not receive credit for removing beneficial effects while trying to complete missions. I.E. wicker man isle, remove attack up and defense up. No credit received even though the beneficial effect(s) is being removed.
Actually, none of my remove beneficial effects work for any mission.
Dozens and dozens of sands of time wasted over a four month period. Any particular reason this glitch is in the system? Am I the only one it doesn’t work for?
And yes, I am using the correct Eddies and toons to remove beneficial effects because I’ve tried a them all!!!
HELP?!?!
