I'm not quite sure what the problem is here...
You wagered this on the 2nd of September, and you were not able to get access to the room on the 3rd? What I can tell you is that the wagering in your screenshot counts for access on the 2nd, so the progress bar would reset at 3 am EEST, as this is when the qualification period ends for the day.

I hope this clears it up, but let me know if you have any further questions.
