Hello FB Community! I hope you are all having an awesome day ;)

I have this thing I am a little concerned about. Whenever I am doing lateral raises with light dumbells,I feel (and slightly hear) my shoulders popping. Does anyone have this too and is this a normal thing? It kind of bothers me while doing that exercise. I don't think it's because of the weight because I'm only using 2 kgs.

Thanks in advance
