Clicks while recording UR 44

Hello!

I’ve just bought a Steinberg UR 44. The installation was OK. The problem is now, when I record with my Shure beta 58A, it sounds (and records) some ‘clicks’ when I’m talking. As I start talking to the mic, it appears the first ‘click’. Do you know what’s the problem and how can I solve it?

Thank you!
