How to make the first day of a week Monday in Relative Dates mode?

I choose Monday
I press the “OK” button
The timeline above doesn’t change

Do you see the question in the image?
【Sat Week 1】then【Sun Week 0】

I want start a week at Monday

And……
Another question:
I don’t want Day 0 or Week 0
For Day or Week:
When “0” exist,“0” is the first、“1” is the second、“2” is the third、“3” is the fourth……
That’s so weird!
I just want to start at 1,like Day 1 or Week 1

Hi @Lunar it looks like you’ve discovered a bug there.

We’ve done some testing, and Sunday seems to remain the first day of the week, even when it updates to Monday in the timeline header. We’ll work on a fix to add to a future version of the app.

Thanks for bringing it to our attention!
