how do I change default vault for saving passwords in Windows 1Password version 8.6.0

This is confusing. On my work computer just this week I set the default vault. Now today on my home computer I'm finding that I cannot set a default vault. Not looking for an explanation of why the differences, just want consistent functionality when I use 1Password. A brand should equal consistency - Heinz ketchup tastes like Heinz ketchup every time; if it didn't then I wouldn't use it. It's these sorts of things that make people move to new products.

As a specific suggestion for the issue at hand, I'd be happy with being required to choose a vault every time rather than finding later that something saved to the local private vault on one machine and now on my phone I have to jump through hoops to find it. It really seems like it's at least 3 different things - OS-level app, browser app, and phone app. 3Password it is.

Additional comment: After typing all of the above, I copied the text just in case. I'm glad I did, because I clicked the button to post the comment, and it had me log in, which lost everything I had just typed. This is a problem. The negatives to dealing with 1Password are adding up.
