Overlay layouts 1.8

I’m having a bit of a issue here with trying to use overlay layouts so that I can have one “base layout” with all of the content which remains the same across multiple layouts and the having several separate layouts which only have the changing region (in a area which is empty on the base layout).
however I can schedule the base layout fine but when it comes to the overlay layouts I cannot see any layouts in the drop down list, is there something I’m missing?

That would be this bug - https://github.com/xibosignage/xibo/issues/1148

As for the work around till 1.8.2 - you can simply create a new campaign.

brilliant, can see them now
