Promotion dates show up as closed rooms.
I set up a promotion starting from 22 November but on the calendar the promotion dates show up as closed rooms (red) because there's no price for those rooms.
The promotion says 40% off the standard rate and the standard rate is shown. It's also possible to book the rooms on the customer site on the days of the promotion but only against the standard rate.
Clicking on the red room dates does not turn them green. What is going on?
