In other words the recorded drum licks are heard on the preceding tracks.
Is the drum track the chicken or the egg? I'm not following which track is the "preceding track". The drums should be live audio from MIDI-driven EZDrummer. You don't ever have to "record" soft synth output. You just "freeze" it eventually if the CPU load of live soft synths and other plugins gets too high or leave it live until you're ready to export the whole project.
Basically, it sounds like you have both Ins and Outs of the UCA222 routed to the Behringer mixer, and you need to make sure you're not recording from the main bus in the Behringer because all previously recorded tracks and live soft synths are going to be riding that to your monitoring system during both playback and recording.
This isn't a SONAR issue, it's an external mixer routing problem. What you need to do to fix it depends on what I/O connections you're making between the audio interface and the Behringer.
