Sorry for this basic problem..
I have 8.3.0 [7995], MyInfoCore 1.12.0+7991 Win 10 Pro 64.
Somehow my girl ended up with 2 Notebooks open instead of just one and I see for the last few days has been posting to the wrong one

The names are
Main one
LEE-JAN2023
(This is what I see lower screen > Notes in Perspec 1454 Level 2 Siblings 168 of 1406 Children 0)
Other one
LEE-JAN2023-Exported backup ( Not sure how that even came about)
(This is what I see lower screen > Notes in Perspec 1452 Level 2 Siblings 280 of 1408 Children 0)
How can I get the extra data from the other version to the Main one? Is there a way to do this.
Then How do I set it up so that only the main notebook shows up every time?
Thank you
