i keep getting this error after upgrading to playmaker 1.41

i am not that good with programming so i dont quite understand what is going on. now it happens every time i run my game after making some changes. it goes away after i reimport playmaker, but comes back again when i change something in playmaker. it doesnt seem to have any visible impact on my game. yet i think i should still try to get rid of it. anybody knows how to solve this problem? thank you!!!!!
