OK if the problem is only with the layers - when you write overlay next to the background you can set the layer there too
example:
with BLACK SQUARE to 0.213 123 218 in zone 1 at layer 65
this way it will be on the layer from the start.
Also honestly I don’t get why people advise making these long lines using AND since it is so hard to find mistakes there and the absolutely same effect you will get if you will have separate lines with &
