Hello. I have a process to read an Excel file, process documents from data, and create correlation matrix. The process runs fine except when I want to add a filter stopwords (dictionary) after the filter stopwords (English) and before Filter Tokens (by Length). It seems to ignore my list of stopwords (dictionary). I've tried using a csv and txt file for stopwords (dictionary) but the stopwords still show up in the output. I've set preference rapidminer.general.encoding to UTF-8. All the files should be in English. Any ideas?
