In the end of the year the same week belongs to CW53 and CW01

Hello,
First let me thank authors for such a convenient program.
I want to report a bug. My calendar is set up to display the calendar week in format Wi. So for the final week of 2020 I see cw53. But when I look at the T-clock dropout calendar, I see that January 1st which belongs to the same week, is marked with week 1.

in my T-Clock it is even named week "0" (zero!)

Mine appears to be OK. Shows week 53 for end December and beginning of January.
