Booking and appointment days mixed up front-end / back-end?

Hi there
I`m trying the booking app ( congrats on its development, by the way :) ). I created a booking on the back end, which I`ve attached a print screen for. On the front end, the Friday slots show properly as being 4 but one while the Saturday slots look like that Friday should be. Please see the front end @

Any help is welcomed.
Kind regards
