Text Pre-Processor doesn't seem to remove stop words

Hi - 

 

I used standard stop words and added others as shown below and ran this through the Topic Modeler:

When sampling the output to show top 3 words per topic, most of the stop words are in the top 3. Why are these words not removed from the mix?

Hi @Kmassey ,

 

Can you show the output of your Pre-Processing tool?

You should have this:

Can you then confirm you are using the Text_processed field in your Topic Modelling tool rather than the original text?

Thank you! I was not using the "_processed" field as the input to the Topic Modeling tool
