Timeline column

When I used to fill in the planned date in the timeline column, I first clicked once on the start date and then once on the end date.
Since a while this does not work anymore.
At the moment a selection is starts with today’s date as the start date. In the example below, I first clicked on 10 January and then on 12 January. Monday chooses to make a selection from today until 12 January.

If I then click on January 10 again, Monday suggests that my end date should be January 17.

If I then click on 12 January, the period 10 - 12 January is finally selected.

I have to click four times for something that should be done in two clicks. This seems like a small thing, but I use this field very often.

It would be nice if someone could explain how I can get the original function back.
