Might have a shim under the bridge bar or piezo element?
But, likely to just get a load of buzz higher up, need to have a look at the relief before nut and action.
1mm or so might be good for a heavy strummer, but 2mm sounds like making issues for string height, intonation etc.
Action 2mm at the 12th... but not relief 2mm at the 6th
String Gauge?
