Problem with Keyword Content Filtering with HTTPS malware scanning enabled

Hello,

 Has anyone tried using the new keyword filtering feature in xg v17 ? I imported a UTM-8 encoded text file with three random words in three rows, then applied it to a custom web policy by adding a allowing All traffic but with keyword filtering rule ,I create a new Firewall/User rule like LAN to WAN > (HTTPS, HTTP, TCP) allowing only my test workstation on this particular rule. The keyword filtering works as expected with only Http scanning enabled, of course blocking only Http traffic. However as soon as I enable Https scanning the firewall will block almost everything even when there is none of my afore mentioned keywords in the URL string. This eventually causes either the firewall or the browser to become unstable with momentary freezes. I was hoping to deploy a few xg firewalls this year but my enthusiasm has been dampened by this a few other undesirable behaviors I've encountered testing this firewall.

 If anyone can shed light on this issue please do for this is not a way for well designed software to behave. 

Thank you,
