Can't show hidden entires on Clover Bootloader

[MacMaker01]

I hid some of my volumes using Clover Configurator. It worked, but once I'm at th bootloader menu, pressing F3 to "show hidden entries" does not work. All of the other function keys do work.

Why would F3 not be working?

Thanks.

Bumping this because I'm getting the same thing and would like to have a failsafe for hiding 'OSX recovery'
