Weebly "duplicate site" not duplicating all pages

[FindingNomo]

I have duplicated my Weebly site which contains about 30 pages, but certain random pages will not duplicate. I've tried multiple times. There's nothing different about those pages - they simply don't appear in the duplicated site. I've tried shuffling the pages around on the original site, eg. to put the missing pages at top, but it makes no difference. The same handful of pages do not copy over into the duplicate site.

How do I fix this?

Additionally, I cannot change the title of my duplicated site. I simply get a red message: Please try again.

Hi there, @FindingNomo,

We definitely want to take a look at this for you. Do you mind attaching screenshots of the issues occurring within your account?

I get this message after a few minutes of processing:

However, half the site does copy. I've tried it several times and it's the same pages each time that do/don't duplicate even when I first switch the order of pages around in the original. There's no functional difference between the pages that do/don't copy (other than the blog, which is one of the pages that will not duplicate).
