Remnant campaigns seem to get priority over override campaigns

[AstridGD]

Hi Revive team! I have remnant campaigns running with a weekly schedule, but once in a while I do big sales for 24/7. 
I tried to have these big sales appear in the game, instead of the normal weekly schedule, by setting up the banners in an override campaign, but the banners from the remnant campaign keep showing. 

I used to deactivate the remnant banners whenever I had a big sale, so I ensured that it would show (reactivate again later), but it cost me too much time, so that is why I tried it like this. What am I doing wrong?

do you mean you the zone keep showing the remnant campaign, no matter an override campaign is linked ?
