Safari Search Bar: If I type in anything that starts with "sc" it auto-deletes (I kid you not!)

When I type into the search bar of Safari, it auto-deletes after the first few letters. This is after my Catalina 10.15.6 update and my most recent Safari 14.0 update.

Here's what happens: If I type in anything that starts with "sc" it auto-deletes the first few letter (i.e., if I type "scatter," the "sc" erases itself, and I am left with "after." This happens on my MacMini and my MacBook Pro. Could someone help with this? Someone else brought this up earlier in post: https://discussions.apple.com/thread/251467695... but still problem persists. Thanks!

Here's what I have determined it is not: It is not a cache problem, not a "clear you browsing history" problem. I reckon it is a Safari 14.0 problem, but I don't know that for sure, just anecdotally based on this problem arising after the new Safari (and new Catalina update) were installed.
