Why does the current flow backwards?

The output of the opamps is set to 15V, if you adjust it to 5V it will not pass a reverse current through the source.

Thank you so much.

The NPN transistor has a diode from the base to the collector, which allows the 15V from the positive rail of the op amp to flow back to the supply

So I should increase the power supply more than 15V, thank you so much.
