Different languages appearing in Results report headers

I have a survey that can be taken in English or Spanish. I have created multiple Results Reports based on the different locations the survey is administered in (1 report for each location). Each of these reports was made prior to adding Spanish to the survey. Now 1 location has spanish responses and all of my reports have changed SOME of the question headers in the report to spanish. Only 2 of the question headers have changed to spanish in the reports but they have changed across all of my reports for this project. Does anyone know how to fix this without manually correcting each one?
