DI100 to POD is recording my backing tracks!

I don't know what I'm doing wrong and have searched everywhere to no avail.  I am trying to record guitar through a Line6 PODXT and to also record a clean DI signal as backup for reamping. My chain is 1) guitar output => 1/4" input on DI100 => output XLR to interface (Focusrite Scarlett) and 2) LINK on DI100 => INPUT on PODXT => Output on POD to second input on interface.  When I do this the clean DI signal records just fine, but the LINK signal from the POD picks up all of my backing tracks rather than just the guitar signal.  I have tried going directly into the interface (no DI) and it doesn't do this, so it seems to be something specific to the interaction between the DI and the POD.  Any suggestions?
