gs.getUser().getRecord() Not the same as GlideRecord('sys_user') ??

Hi All,
I'm getting different results on two things I thought were essentially interchangeable.

var usrID = gs.getUserID();
var gr = new GlideRecord('sys_user');
if(gr.get(usrID)) {
     gs.print(gr.getValue('u_default_group'));
}

OUTPUT: 6f028386d0aea0007f0059dfebc05518

var gr = gs.getUser().getRecord();
gs.print(gr.getValue('u_default_group'));

OUTPUT: null

The 'u_default_group' field is the only field we've added to the table that doesn't work, but it's also the only reference field we've added.
I know

gs.getUser().getRecord()

returns a 'GlideMemoryRecord' not a 'GlideRecord' but is there a reason why this specific field doesn't work?

Thanks in advance

If you log out and back in, does it work? Perhaps the GlideMemoryRecord gets cached at login.

Thanks once again CapaJC!

I did not know that it was cached.
