Scheduling does not work

Hi,
I set a start date in the future for an ad but it’s always showing already. (Until I have a solution I disabled the ad, so there is nothing to see on the website)
I used the widget and tried
1) selecting the ad directly
2) using a group (and also set the same start date on the group)
3) using a place
Did i miss something?

Thanks in advance!
