Can't edit field on issues

[yoga.pramono]

Already check the permission scheme and the workflow.
Its granted and there's no condition or validator

Is there any option where to check the configuration?

Thanks

Hi @yoga.pramono ,

Please check if the field is added in "Edit Screen".

i.e. Go to project settings --> Screens 
Check what is the screen scheme assigned for the required issue type and modify the assigned edit screen.
