Pico CMS / display bug in dashboard when disabled

hi, i’ve installed pico and created a web-page.
Then i’ve created an external link towards that web-page.

Unfortunately, settings don’t offer to limit the usage of pico to certain groups.
So i’ve disabled it, thinking the web page would still show: but no.

Instead, a looping bug integrates the dashboard over and over each time i click the external link (world icon):
