Writing UIFlow2 firmware with M5Buner causes certain pins to go HIGH

[k-sa]

I am making a device that uses two Atom Lite devices to communicate with each other via BLE. When the UIFlow2 firmware is written, G21, 23, and 25 output 3.3V.
G21 is one of the outputs of the ATOMIC H-Bridge Driver Base, so the motor starts turning on its own.
This does not occur in UIFlow, but only in UIFlow2.
Is there any way to resolve this situation?

By the way, when the program is executed, it works as per the pin operation in the program.
