Strange sort behavior

[Barlin63]

I have found some strange sort behavior of which I am not sure whether it is a feature of a bug. See the picture below were I have sorted the hands on date and I try to resort on chips won but it looks like the date sort is fixed. It also shows a "1". Not sure how to activate or to deactivate it. Any suggestions?

If you hold ctrl and click on a column it adds a secondary sort by that column and labels the columns 1 and 2 that it sorts by. If you click on a completely different column without ctrl held down it should drop the primary and secondary sort and sort by the new column you've clicked on.

Great feature. Thanks for explaining.
