Using jei version jei-1.16.5-7.7.1.129 its saying use configured mod to access ingame config. i have configured version configured-1.2.0-1.16.3 it still gives me this error. i dont know what to do.

Thanks for the report!
This has been fixed in the latest versions for JEI for 1.16 and 1.17

Can confirm it, same versions. Not game breaking since config from the file still applies.

yes i can change it in the config in the file just not in game
