Hello, The calendar is presenting a weird behavior where 9 days forward, counting from today, are always blocked (the day is red and there is no available slot). Checking the appointments, there aren't enough to fill every slot and every day. Date range: from 2021-09-01 to 2022-03-22 The service have 2 slots available from 08:20 to 13:00 and 14:00 to 15:40. With 20 minutes between appointments There isn’t any vacation for those dates. The problem occurs only with the worker "Atendimento Presencial" used by the locations "Subprefeitura Cidade Tiradentes – Rua Juá Mirim s/n." and "Centro: Rua Barão de Itapetininga nº 221 - 2º Andar" https://fundospda.com.br/agendamento/ Already changed the worker to a new one and the problem persisted. It seens some kind of a problem in the calendar/appointments. --- WordPress version: 5.8.3 and 5.9.1 Plugin version - 3.7.3 and 3.9.1 PHP version - 7.1.31 and 7.4.15
