Error ... several actors listed in both S1 E11 and E12 who I believe are only in E12

Someone with more knowledge and skills than me might want to look at https://www.imdb.com/title/tt0601558/fullcredits/?ref_=tt_cl_sm

The full cast listing includes Virginia Keehne (but spelled Virginya) and several other people who I believe were only in the next episode, E12, where Virginia's name was indeed spelled Virginia. 

I just went back and undeleted my DVR recording of E11 from several days ago, and had not yet deleted E12, so if someone needs me to play/pause the credits on E11, let me know.
