Copy and paste layers from one slide to another

I built on the master level and have two layers for menu and transcripts. I have that on the Main/first slide in the master view...I expected this to be inherited by the rest but that was not the case...tried to right click on the layer so I could copy it to the other layout views...that didn't work. I then tried to use the copy feature in the layers panel and drag and drop it into the other layout. That didn't work.

Am I understanding that the only way to get the layers into the other layout designs is Ctrl+A/Ctrl+B and add both layers to each layout?
