Yes, that is odd. Which template did you initially assign to your compute node after you installed the HPC pack on it?
If everything's working fine, then you might like to double-check whether the individual node templates are actually named correctly. If you just want to make sure that your compute node shows up as being associated your "pre-configured" node template, then
it's OK to assign the template to the compute node again. i.e. Once you're sure which is the "pre-configured" node template, you should be able to just take your compute node offline and assign this "pre-configured" template to it.
