Multiple computers reporting to SEPM as the same client

We have about 7 machines that were deployed for a team to use for processing. I've just noticed that they are all only reporting as one client. By that I mean when I find it in a folder it will say desktop1 and when I refresh it could say desktop5 or desktop2. I'm thinking they were not sysprep'd properly by the team that imaged the PCs. Their Unique ID's show up as the same in SEPM. Is there anything I can do from SEPM to resolve this?
