H2C Clicking noise from Print/tool head

Bambu Lab H2 Series Bambu Lab H2C

Brand New H2C making clicking noises while printing using the left hotend. I have not pay too much attention to the right hotend so I cannot say is only the left hotend. It looks like the clicking noise occurs during retractions but I have no idea what causes it and how to fix it. I already opened a Bambulab ticket however wanted to check with the community if someone else have faced this issue and how it was fixed. The prints came out good is just quite annoying the clicking noise and I fear there might be an issue later on.

I have triple checked that it is not the PTFE tube be printing without the top glass. Also in case some one ask the filament was dried for 8 hours before printing.

Unload filament, manually heat up nozzle, then press extrude-retract-extrude… Repeat and see if you can recreate this without z movement
