Added services not showing on calendar?

I recently added dog walking and drop-ins to my services for the summer; however, they only appeared for the remainder of this month (which is April - too early for summer).

The plan was to manually adjust openings to '0' until the beginning of June so people who are planning ahead would know I'm 'out there.'

Instead, the only things listed after April 30 were my usual daycare and boarding spots. Since this was not helpful to me at all, I disabled the new services altogether until this gets figured out.

Advice? Has this happened to anyone else?
