Rotary encoder guru ?

[v12nut]

Hey, I have been having trouble with the use of the KY040. I have used the GitHub repository that was mentioned in one of the above posts and the encoder works. the only problem i have with this is this, the encoder only turns the volume up, no matter which way the encoder turns  it only turns the volume up. I have everything wired the way shown in the plans on GitHub. Any ideas on what is causing this?

I have the same problem in reverse! my encoder only turns the volume down
