Two reference lists in same doc after updating EndNote

Hi

I updated to EndNote 20, and now new references are added as a new list at the bottom of the document. The old list is still there, and the fields are active (go grey when I click them). It isn’t fixed when I click update bibliography and references.

I tried exporting the travelling library to the library I am using, but to no avail (it just carries on as before).

Any advice? It would take me days to re-insert all the damned references, so I really need to sort this…
