Can't Hide Headers (Fences v5.53)

Exact Windows version \ build (winver.exe): Windows 10 Version 22H2 (OS Build 19045.4412)

I am using the trial version of 5.53.

Created my first and only group to be hidden by Fences.

Trying to hide headers so they only show "On Mouseover":

This behavior exists even after rebooting the laptop.
