Problem with xxts_v2 using model_path vs model_name

[JimmyInsane]

Hey there,
first of all, great project! I love how good the output sounds.
But i have a little problem:

When using mode_name with xtts_v2 everything works perfectly.

Now as my C-Drive isnt that big, I copied the stuff over to another folder.
To now use the model I change model_name with model_path and config_path.
Generation works and gives me output, but the voice is like half an ocatave to low in comparison to the reference_wav.

Any idea what I could do to fix that?
