Hey Donald,
Welcome back! I got a new keyboard for Christmas, so I’ll have to check your site out! Now, down to business 🙂
What you’ve described sounds like a possible bug. I’d be happy to test to see if I can reproduce the issue. Please visit Events > Imports > New Import and fill in the screen as you’ve been doing thus far, then take a screenshot and send it in addition to a screenshot of your Events > Settings > Imports screen. I’ll also need a Facebook event link you’ve been using to test.
Thanks and I look forward to your response. Cheers!
