Ztmonitor tool question

ztmonitor tool
trying to fine tune a new install where the pots lines sound horrible. I have looked at some tutorials on the ztmonitor tool and they all show this:
<---------(RX)---------> <-------(TX)-------->

When I run it I get this:
<---------(RX <---------(TX
I’m not sure where my audio levels should be because it does not look like the entire graph is showing up.
