Thanks for the feedback/advice Moiraskye, but I don't think any of your points apply to my situation/problem:

I am not using the app, I am on a laptop/desktop and not trying to do an interactive location while out driving...I'm trying to enter my home/office location as a favorite.

As it turns out...what I did was log off, exit the website/close the tab on my computer and open a new tab and re-log in again.  That worked.  Furthermore, the same situation happened AGAIN, but this time while I was entering mileage accumulated for a previous trip (again, on the laptop/desktop computer, not on the mobile app).  What I ended up doing was refreshing my webpage, and that seemed to fix the issue.  I must say, the QuickBooks online seems pretty crappy if it is having these types of "issues/bugs"...especially considering the price that is being charged.  Not professional at all IMO.
