I had something similar on my 2015, unfortunately I did not see it until out of warranty
Definitely make Jayco fix it under warranty.
The issue is that the track that holds the bulb was deformed by poor assembly and will likely keep falling out. This track is on the inside, near the ceiling, attached to the wall, and somewhat difficult to access. To do it right, you would need to pull the inside facia. Thus my recommendation to have it done under warranty.
In my case I, because it was out of warranty I cut a couple of small holes in the bulb and then screwed it into the track, to make sure it did not fall out again.
