CSV Importing issues

I have had a couple issues trying to import via CSV from Collectr.
The first main issue is that literally no cards match even though if you click the pencil and edit it, it comes up immediately. I have to go through and click EVERY pencil to confirm each card before it becomes Valid.

Also, when I was doing this occasionally the pop up pencil box to select the card would popup and disappear, not allowing it to come back up on any card. Basically forcing me to import what I had done already or cancel completely and start from scratch. This was extremely frustrating and happened multiple times.
