Code not downloading, Pros

I am having problems with pros when downloading code. The CLI and Toolchain are both installed (Fixed the problem a couple of weeks ago), but now when downloading code, nothing changed. My driver control code/Auton code is downloading, but the robot doesn’t do anything that was coded. I tried to switch the drive to arcade, but the robot stayed on tank, and when I tested auton to change PID, it ran the old code even though it was already deleted. Im not sure what is going on.

You probably didn’t save the code before downloading.
