Duplicate column name error in Scorer(javascript) node

Hello Knime Team, I keep getting this error when I use scorer about duplicate column names, but the column names it says are duplicate are labels in the predicted column.

The Error : Configure failed (IllegalArgumentException): Duplicate column name “heart disease” at positions 13 and 14.

But ‘heart disease’ is a label in the Target column.

I’ve attached Screenshots of my configs in case if they may help and if there is an error on my side

Hi @Pradyum! This sounds like a bug. Which version of KNIME Analytics Platform are you using and how is the “Scorer (JavaScript)” node configured?

Hello @leo_woerteler, I apologize for the delay in my response, I’m using 5.2.1 and here are my scorer configs

The rest of the configs I didn’t change, I just changed the predicted column and actual column.
