Tree Ensemble Learner does not recognize newlines in column names (include/exclude filter does)

I am trying to use the Tree Ensemble Learner node for feature extraction.

The target column is not showing columns that have newlines in them. Unfortunately, the data that I downloaded has newlines. On the other hand, the Include/Exclude filters are showing those attributes.

(Side note: it would be nice to have a search/filter option for the target column just like include/exclude filters. there are way too many columns in my dataset)
