Appointment + shows no available date (till end)

Hi there,
Last weekend, Appointment + was not showing any available date, for none of the available service providers. What can be happened? It seems fine now.

Besides, the calender shows the sentence 'tot end' (till end). This is new. Can it be changed by a date or can I remove it? See attachment.

And when can we expect fixes for the latest bug, see my other posts.
