Can't edit layover at some POIs using trip planner

I've created a route from Grand Canyon to Reno. Using the slider I've added POIs ~every 100 miles for fuel and stretch my legs. On a few it won't let me change the layover time from the default 30mins. I've deleted the trip and recreated it a couple of times without success. Anyone else having this issue? Any suggestions?

PS. This starts at the same point along the route. CA190 death valley.
