Hola Julie
In this sentence "todo" is not referring to "maleta", it is referring to a "everything" and for this we use "todo" (singular masculine form). There's a note by the end of the lesson that explains this: "Note on todo/todos". There are two examples in the lesson for this part:

Yo quiero verlo todo. 
I want to see everything.
Todo me parece interesante. 
Everything seems interesting to me.

I hope it clarifies it.
