So, I was forced to use an array formula to get multiple results on matches, and the formula works.

The problem is, when I try to edit the data the formula is using, it basically breaks. Do I need to do something special to edit the data, much like pressing Ctrl+Shift+Enter to enter the formula in the first place?

It's probably something really simple, but I am new to array formulas. They seem to eat space quite quickly also.
