XR15 Remote not pairing with my Polk 9500BT soundbar

I am trying to program our new XR15 X1 remote with our Panasonic TV and Polk 9500BT soundbar without any success.  With 1-2 codes, I am able to get the mute to work and the Volume Down button works to Increase the volume.  The Volume Up button on the remote doesn't do anything.  I have tried every code I could find online and from the tv screen.

When I look at different instructions online, some reference holding a setup button, but the XR15 does not have one.

Thanks.
