ZPM folder huge with Agent Defect 533031 installed

We have installed the Agent Defect 533031 (kmviewer.saas.microfocus.com/ on our devices but we have our Machines do a refresh every hour ...

But i checked and as stated in https://kmviewer.saas.microfocus.com/#/PH_210057 it is only keeping the last 7 Days.
(This ends up beeing still kinda excessive as this ends up being a little over 12GB)
