Troubles copying triplets

I have a passage with repeated triplets and earlier hid the numbers and brackets using the Properties panel. I now want to copy and paste several of those passages into other instruments but the triplets don’t copy and the music therefore takes up additional bars and is in the wrong rhythm. There wouldn’t be a problem if the numbers and brackets were showing and I included them in the copy but I have been unable to find a way to “re-show” them. Is there a way to resolve my quandary?

If you show the tuplet signposts (View>Signposts…) , they are selectable and will copy along with the notes.
