Weight difference between Zwift profile and Companion app

Hi, I was just logging in to update my weight and noticed that there is a difference between the value shown in my Zwift Profile on web and my Zwift profile in the Companion app…

Can anyone explain why my weight value on Zwiftdotcom / profile would be different to Companion app -> More -> Profile ?

I would have thought both would be synced?

Which one does Zwift actually use to calculate my w/kg in game?

Which one does ZwiftPower actually use?
