[Python] Column named read as tuple instead of string in pandas

I have a column ContentVideo that exists in pandas df.

Trying to do this trasnformation

data.loc[data.ContentVideo == 0, "play_rate"] = 0

however, when I am getting this error

I have verified that "ContentVideo exists as col name in dataframe.
