trusted vendors list lost vendors

Hello!
I have problem with CIS last version 4…920.
OS - Windows 7 x86
Antivirus - Free Avira 10
CIS Proactive, Defense+ = Clean PC Mode, Firewall = Safe Mode, Sandbox disabled, Comodo antivirus not installed.
After using cis some days, i see that defense+ warning me about every software action, for example firefox browser, then i see that trusted vendors list is empty, but it was full with vendors.
After diagnostics repair and restart list is full again and this problem repeated after some time.
Thanks

yeah I noticed that also it has happened on two of my computers already. It’s very weird, it could be something to do with the update process? I hope the devs see this and address it becasue it’s a very important part of CIS.
