Persistant Password

[Grizzly]

Hi All

I have 18.04.3 & 19.04 LiveUSB's with Persistant storage, when I boot I get a 
choice to use Persistant or Try without installing (plus many more options), 
only problem is that now if I try to run Persistant it asks for a 
LiveUserSesion Password, and I can't get past that, I can "Try without 
installing" that seems to make Persistants pointless

Any ideas
