issues using microphone with garageband

I have just started to use GarageBand to record voice overs and have purchased a ZealSound K66 microphone. When the microphone is attached I can select it as input with no problems however when I use it there is hardly any waveform showing in the track. I am on the latest version of GarageBand 10.4.12. When I use the microphone on a different laptop which has version 10.4.8 it seems to work fine. Any ideas why my set-up is acting differently??
