Size of a column not changeable

Hi, I try to change the width of the last column, what is not possible.
Here in my example the column “Dauer”

The other columns the width is changeable by moving the double arrow between the columns.
What goes wrong?

I don’t understand the question. Your column “Dauer” is the widest on the screenshot. How did you manage to make it that wide if you can’t change its width?

Use the LEFT border to resize the width; the one between Dauer and Kosten

Thanks, I will respond next week

Thanks, Manuel
I will continue testing next week.
