Welcome to our forum.
I am not sure how you export and import, in latest version we have included export and import feature, please try this, check the documentation here.
How to Export/Import Accordion?
Let me know how it works.
Glad to know that, if you love our support and plugin please submit us five-star reviews https://wordpress.org/plugins/accordions/
It finally works as it should. Thank you very much for you help and patience! 🙂
if you found all accordion is exported correctly then that's ok,
before import on new site, you will need to delete all accordion from the new site(where you are importing) make sure trash is also empty,
then run the import. I hope that will work.
