Two vaults with identical names

Thanks. Jack P. I don't think I have a family account since I don't need one. How would I find out? If I don't have one, I'd like to move all of the records in the second Personal vault into the first Personal vault and then delete the second vault. Can I Select All in the second vault and move all records at one time into the first vault?

I thought I read in one of the question threads that the extension code and the app code were on different schedules and therefore had different version numbers. I take it that is not true for MacOS and Safari, right?
