Changed text from User Interface Text, error"Context Value Source Of Data is not in the list of valu

Hello,

I needed to add a DFF in the Measurements section in Goals. however, due to the unavailability of configuring DFFs, I changed an existing field name from User Interface Text which is the "Source of Data"

Goals is integrated with the Performance, so when we created the Performance Documents and reached the step of submitting the evaluation by the manager the system gave an error "Context Value Source Of Data is not in the list of values."

As the manager evaluation is the last step. however, when there are further steps in the Performance Flow, Manager could submit evaluation without an error.
