PDK down change not seamless on 718

[Purespeed]

when pulling up to a junction and as the PDK goes from 3rd to 2nd and from 2nd to 1st I get a slight clunk/knock as it changes. It feels like the engine revs are dropping off too much and when the change is initiated the engine has to catch up making the transmission clatter a bit. I have owned a 981 PDK previously and don't remember it being like this.

Am I worrying about nothing?

Thanks
