Payment Type Displaying Duplicates

I ran into this today. I was trying to add a payment method. Once I added a method the screen gets truncated and the list disappears. Anyone working on this glitch?

That was the first thing I checked was the data. The screen you are looking at is a fresh install. If you go to any of the demos that @brady has listed. It does the same thing.

The only way I could get my entry into the table was that I had to manually enter it into the table my self by SQL insert. Once I did the SQL insert, the entry was duplicated onscreen. So, it is a code bug, not a table entry that is duplicating the entries that are inside the table.
