Search while in the Main 1Password window no longer displays only the matches

No problem about the delay. I'm very appreciative that you have this forum and respond as well as you do.
I see about the anti-virus. Yes I have Web Root as my internet security. The reason I reported this is because it is a change in behavior. One of the two apps (or both) seems to have changed.
About the search. I now see that the sorted items are appearing in a drop down and when you select one of the items in the drop down, that is the item displayed. And, yes, with (ctrl+enter) only the filtered items are displayed. Again this is an unanticipated change in behavior.
I may be wrong, but I guess this is the Agile Development style in action. I've never been a fan of that because of the constant change in behavior from one month to the next. I was an old school software developer and I prefer major updates, say once a year at most (except for bug fixes). Then user's expect major changes in functionality and they are documented.
I'm pretty good, but how is a user to figure out that a command like (ctrl+Enter) even or now existed? Almost nobody reads the release notes, I suspect.
