Hello Zeljko,

Thank you for reaching out to us.

At the moment, there is no option to add to the calendar where there are no available events on that day.

Can you please let me know what exactly does not work with update?

Please try the following CSS to hide the filters:

.amelia-app-booking #amelia-booking-wrap #am-event-calendar-page.am-wrap .el-collapse-item__content {
    display: none !important;
}
.amelia-app-booking #amelia-booking-wrap #am-event-calendar-page .am-event-header__right {
    display: none !important;
}

Let me know if it works or not.

Looking forward to your reply.
