I am traying to add objects to layers in my doc, I have created a context layer for my org chart, and have successfully added a couple of objects to my “Context” layer. I am trying to add a set of 4 smart containers, following the same process as the other objects: right click > Copy or move content, but the layers option does not show up. (see screen shot).

When I select just 1 of the 4 smart containers, and follow the same process, the Layer options shows on the drop down but is greyed out:

Please help.
