I've been using version 8 for a while and works fine, I was wondering, from the screenshot, what can I safely uninstall from past versions? Thanks.

if you do not need to v7 then you can uninstall the 2 Chronoforms7 items along with the ChronoG3_Plg
The issue is having outdated extensions from older CF versions still installed.
Uninstall the two ChronoForms7 items and the ChronoG3_Plg plugin if you no longer need version 7 functionality.
