The I Love Lucy Quiz

I Love Lucy is one of my favorite TV shows, but I'm having a little trouble finishing this quiz. I go through everything, and I get to the part where it says "What is the name of the star couple?" Since I don't know what to expect, I try Lucy Ricardo and Ricky Ricardo, but it won't take that. Next I try Lucille Ball and Desi Arnaz, and it still won't take it. So I give up, and I scroll down to see what I missed. It says "The Ricardo's," and I was shocked because to place an apostrophe between the o and the s, makes the name possessive, not plural. Who would guess that on their first try? Please fix that. Furthermore, even when I enter the name the way it is listed in the correction, the quiz still won't accept the answer. Finally, the quiz asks the same question two times when it says "What ethnicity is Lucy's husband?" and "Where is Lucy's husband from?" I am a little disappointed, but I love the idea for the quiz. :)
