Line Troubles

I found a person with a family surname in a cemetery, I looked her up and found out I was related to her through my maternal line. I found a bunch of cool information through her and was very excited. I came back in today and started looking into her again and now all the information I can get is through my paternal line. I think it's cool I'm related to her on both sides, but now I can't get it to give me any information about her through my maternal line. Is there a way I can switch it back so I can finish my research?
