Issue with 04 ROC function from Result Interpretation

[SorinVatamanu]

After obtaining susceptibility layer with "y" for landslide presence or absence and "SI" for susceptibility index, when selecting those parameters under ROC, the following error occurs,

Traceback (most recent call last):
File "C:\PROGRA1\QGIS341.5\apps\Python312\Lib\site-packages\pandas\core\indexes\base.py", line 3805, in get_loc

The above exception was the direct cause of the following exception:

It ignores the field names I pass (STRING='SI', STRING2='y') and instead hard-codes df['y']. Even worse, in the same code path, the plugin builds df using ONLY the score column, so y is never added to the DataFrame at all.
