I've found that I was not able to select Assign To field, digging the code I've found that handler_is is supposed to have 'handler' as key to localization files, but there is no $s_handler but $s_assign_to.
My suggestion is change logic and display ANYWAY field no matter localization exists.
Going to create PULL REQUEST
