Aggregation problems

Hello,

I have a "content" view that I display the top 20 terms ordered by their number of nodes associated. The normal result is like this:

Term Y (15)
Term X (12)
Term Z (6)
.........

I am achieving this by the "Use aggregation: Yes". Sort field is "COUNT(Content: Title) (desc)"

This normally works on an unformatted output. But feed is not sorted by the numbers. Instead it is sorted by term name. From A to Z.

Attaching the views export.
