How do I resolve the error UI Error e.replace is not a function

@raminar, 
can you share your process?
It's important in order to reproduce the error and to find a solution.

The process is as follows: I upload .csv file for a classification model. Then I select column I want to predict. Next I try to add the gains and losses. That is when I get the error.

I am using your online model and not an app. How do I make this information available to you?
