Flip books settings are gone after export/import of site and database

Hello!
My name is Staffan T?rner.
I manage my site staffantorner.se.
It’s not comercial, it’s a hobby, but important for me and my relatives like it very much.

For testing that I have a working backup I have set up a beta site, beta.staffantorner.se .
Everything works fine except my Flip books.
After export and import of the site and the database the settings and the toolbar for my flip books are gone. The “corrupted” Flip books are there.
(Of course I have made nesessary changes in wp-config.php and in the database.)

Example: https://staffantorner.se/library-eng/books/jon_i_slatthult_library/
Compare this with the beta site:
https://beta.staffantorner.se/bibliotek-2/bibliotek/jon_i_slatthult_biblioteket/

I have made a screendump of the databases and you find it here:
https://staffantorner.se/z-dig-pub-supsystic/

(Erlier I used a similar plugin from Ready! but when I found yours it looked much better so I moved all my book to your plugin. I have erased all books and pages for Ready!’s plugin and deactivated it before I made the export of the site and database.)

(I had a similar broblem with Ready!’s plugin. All settings were gone, but tho toolbar was there after export/import.)

Can you give me any hint for a solution of the problem?

Best regards
Staffan
