the SignaLink USB is an audio interface with an internal VOX circuit that keys your rig directly when Tx audio is present.
The "Test PTT" button in WSJT-X does not cause any audio to be output.
So in summary, you have duplicated PTT function via your CAT serial connection and via the SIgnaLink. That may be OK but I recommend setting the DELAY knob on the SignaLink unit to minimum. You should not expect to see any power output when using the Test PTT button, nor any indication on the SignaLink unit. To test Tx power use the "Tune" button on the WSJT-X main window. You can also set "Settings->Radio->PTT Method->VOX" and let the SignaLink USB do PTT for you.
See this post for a recipe for correctly setting Tx audio levels: https://wsjtx.groups.io/g/main/message/13890
