Some people have had success blocking off the area they are laying in. I didn't when I tried, they laid next to what I put there, but we get different results. If it works for you great.
The weekend is coming up so you may have a chance to do this. I made a couple of my nests so I could lock a hen in there if I wanted to. That's come in handy for a few different things. When I have a hen not laying in the nests like yours, I wait until she is on that bad nest and move her to a nest I want her to use and lock her in there until she lays the egg. Usually that takes about a half hour after I lock her in but one hen took 3 hours to finally lay her egg. Usually I only have to do that once and they learn that the nest is a better place to lay. Usually.
Sometimes I can pick her up when she is on that bad nest but usually she runs off. I chase her down with a fishing net. First lock the coop door and pop door so she can't get out, makes it easier to catch her. Yes, she usually gets quite upset, especially if I chase her around the coop with a fishing net. But I'm OK with her associating that bad nest as not a safe place to lay. The real nest is a lot more calming.
Try to keep the eggs cleaned up in that bad nest. If they see an egg laying there they might think that is a safe place to lay an egg. Also, put a fake egg in the real nests. That might encourage some to lay there.
Good luck.
