Looper settings

I'm a new user. I was getting used to the looper, record one sound, overdub a second, then solo while it loops.

I just updated software, downloaded rig manager, etc.

Now when I loop, record one sound (vibrato), go to overdub with a different tone (clean chords) the loop changes with whatever tone I select and I can't do both.

I'm stuck here and can't figure out how to overdub different sounds which will impact live performances, I'd rather not drop the songs. Anybody figure out how to get around this?

Thanks paults, I figured it was something easy just a matter of finding these things as I get up to speed!
