Beta scripts appear when loadbeta is disabled

Tl;DR: How does pyRevit hide beta scripts - it doesn’t seem to be working for me.

Howdy folks, I seem to be having issues with beta scripts still appearing in my toolbars even though loadbeta in the user config folder (%appdata%/pyrevit/pyRevit_config.ini) is set to false. I have isbeta: true in the bundle.yaml file (based off of this page) as well as __beta__ = true as the first line in the script itself (based off of this page) and when I launch Revit the script still appears. Is there a way to better understand how beta scripts are filtered? Currently worried that end users/non beta-testers are able to run beta/in development scripts.
