Format Editing (strange moving up/down of columns)

I'm not sure if this is a bug in DO 12, but when I edit a Lister Style / Format / Edit

and move up or down a selected column, the column isn't selected anymore and when I want to move it up or down a 2nd time I've to re-select the column before I press up or down button.

A little bit strange when I want to bring a column up from bottom to top or vice versa I have to select the column to move x times.

This is fixed in the 12.1.1 beta, which you can update to now or wait for 12.2 next week.
