Something very strange is happening in my calendar today. I am trying to send a Special Offer to a guest. However, when I click on the calendar showing 10 August, straight away it skips to the calendar for October and highlight 8 October. Obviously one is 10/8 and one is 8/10 but it is not allowing me to select the correct dates. Very strange. It is as though there is some software formula playing up in the background. I have never experienced this before and often send special offers.
