Honored ContributorWhen running Fitter(Place&Router), I get the error: Can't place multiple pins assigned to pin location Pin_K22 (IOPAD_X77_Y33_N14)
But when I check my pin planner, there is only one signal assigned to Pin_K22. (screen shot attached) What can be the possible reason for this fitting error? Thank you.
