Daniel started to help me in the customer support email, and he stated something about the promotions appears to not be local. But I knew I only promote local, so his comment lead me to one thing after another and I tried to promote without the local promote box text, I'd delete the text but keep the box, thinking I could just have the image and caption displayed without introductory text, but it would not go through.
So, I added text, just a few words, and the promotion went through, it displays.
I did not delete the local promotion box, I just deleted the text from the box, and that was enough for it not to schedule and promote. Don't know if that's a bug or not.
