SOLVED: The iphone vault is updated with an old one from the Mac, instead of the other way around

Environment: Mac OS Big Sur with 1Password 6. WLAN synchronization between Mac, iPhone and iPad.
1- I have erased the hard drive and have done a clean install of Big Sur.
2- I have a backup of my vault from May 2020.
3- After installing 1Password 6 in the new Big Sur (it asks for a license, which I have lost) I used the old backup I had.
4- Then I have synchronized (WLAN) the Mac with the iPhone. I thought the Mac's vault would be updated with the iPhone's, but the result has been just the other way around: now the iPhone has the data from the old backup, the one the Mac is using.
5- I have not synchronized the iPad, so as not to lose the information.
6- The question: is there any way to update Mac and iPhone with iPad data? Can I somehow save the vault that I have on the iPad?

Thanks a lot, guys, and sorry for my English

2- Copy backup to Mac using Finder
