Perfect Week Streak Bug

-Description of every single step you made until you encountered this error-what did you do, what happened?
I experienced a disruption in my perfect week streak despite completing all planned sessions. Initially, I scheduled three sessions for the week and completed them, receiving a perfect week notification. Subsequently, I added a fourth session and updated the weekly target in Freeletics accordingly. Although I completed this additional session, the application did not recognize the prior week as a perfect week in the following cycle, resetting my streak to zero. It appears that modifying the session count from three to four after achieving a perfect week affected the system’s calculation.

You can see on my screenshots that August 21st I had a perfect week, August 22nd (my 4th training session of the week) I did not have the perfect week badge (which makes sense as I had it the day before.

Then you can see that on August 28th, I get the badge 2-week streak (but I have had perfect weeks for more than 200 weeks) so I should not have a 2-week streak badge.
