Do you have the Global Listener enabled in DashBoard on your panel?
on the Toolbar -- Window - Preferences - RossTalk GPI Listener Enable -- also set it to 7789 and then modify your device config for sending to the panel.
TD Panels may have port 7788 reserved for the Panel to run it's rosstalk listener and best to put DashBoard on a different port .
Then also make sure your button "trigger ID" has that GPI value in it that you are showing. I also see two "new custom panel grid" files open. You might want to make sure you don't have two different things running either
