I suspect that they have not been consolidated into the compost sufficiently to find enough water yet. Did you saturate the plants before transplanting?
It has been quite dry this spring here, in N E Hampshire, Uk and soil conditions are relatively dry.They may recover, perhaps you need to water them and pack the compost tighter around the clumps. One of the joys of gardening is seeing your transplants suddenly show that they’ve made contact with ground zero and are away!
