Only one lap for entire session

I am racing at Hallet OK counter clockwise. Did 10 + laps but only one long lap of 20 minutes recorded. Can I break this up into the actual laps? See the map attached, it's odd.

How do I make sure it doesn't happen again?

Thanks.

Also says my top speed was 68 miles per hour when it should be over 100 miles per hour. The map looks like I drove way off track sometimes.

The spikes mean you had bad GPS reception. That's the cause for wrong speed displays too. Please check your mounting position as written above. iPhones have a pretty consistent GPS quality, so it really should be around this issue.
