Does not import the template

Hello!

I find it difficult to enter my template and then save.
I created a template with editor of PluginOps. Then I saved a new template, I gave the name and then I selected the template saved before and imported into the new template. As soon as I click on Update displays “Are you sure ? It will insert the temlate below your existing content.” Click ok (seen seems to properly inserted the template).

However appears this inscription: “There is some bug which is preventing this page to be updated, contact the Bug Killers “. Click on editor and enable editor and I do not see any imported structures.
Can you help me?

Thanks
