Hi,
I'm using PowerPoint 2016.

I try to copy several slides from one PowerPoint document to another.
Some of the slide do copy correctly. I get the template and the content.
But some of them don't. It does not copy the template just the content.

Does anyone has an idea why?

I made the template of the one I try to copy and there is nothing special about those slide that doesn't work.

For test, I tried to copy those slide from the SLIDE MASTER to the SLIDE MASTER of another presentation and it did work.

Thanks for any help
