Working with the native muse light box, put it on the wrong page, I'm selecting everything bit of the container but it won't copy except for the text fields, why and what am I missing?
Click the composition only once, copy it (patient, takes a while, because it copies all breakpoint informations and all settings),
click/open the desired place, paste it.
Additional – (right click) cut it out (scissors) - paste in place.
You then don't have to delete the composition.
