S5ii "This menu item can't be set" loading Lumix Lab LUTs

Hey all, new to my Lumix S5ii and was excited to use the real time LUT feature for casual content creation.

I have no problem creating new LUTs or downloading creator LUTs and sending them to thecameras. However, when I try to load up the LUT from the LUT Library, I get the message that "This menu item can't be set". Surely if it's from the Lab app it's in the right .cube format?

Also, taking the SD card out there are no LUTs loaded onto it.
