I have just set up my solar system and my mppt don’t show a negative discharge on the batter in the app will only show a plus charge when in the sunlight.

Smart solar 75/15
This is normal.
You need a SmartShunt or a BMV for that.
Edit:
I forgot that the small chargers have that dedicated load output and your question might be about this.
That one should indicate the current and power drawn by the load directly connected there.
