Is there a bug creating a route on Garmin explore?

I was still able to create my own hiking route on Garmin explore until monday. Today, I want to make another path. I click a first time to create the startpoint, a second time to mark the next turn, but instead it creates the endpoint and the way in between doesn't follow the road it randomly goes somewhere even not following an existing track. You can see on the picture.

I noticed it does that only when I'm around my house. If I create a way far from it, it works perfectly.

I didn't change anything in the settings.
