That makes sense, thank you so much! I thought I was messing with a type error, which threw me off. That makes sense why Distinct() won't work, because you can have the same item in the list more than once, it just has to be seperated by something else first. Thanks again!

That's not really a type mismatch, it just looks that way. The real error message is the Values differ at index [4] underneath the type mismatch line. Distinct() won't work, though, because not all elements in the output will be unique, look at the examples again.
