Clicks / pops when reverse button pressed on XDJ-RX V2.21

Hi guys, I'm not sure if it's just me, the new firmware version 2.21 or its normal . But I've just noticed that when pressing the reverse button I hear clicks and pops. Easier to hear on more ambient parts of tracks.
This is not cool.
Is it just me?

* Edit

Yeah guys this is a big issue with the new firmware 2.21

My mate has 2.10, used the same USB and same tracks as me without any pops when pressing reverse back and forth.

I have tried with just headphones also 

Can I please be advised how to downgrade the firmware ASAP as I need this for a big gig this weekend and use reverse alot.

Alternatively we need a fix for this..

Please!
