I can't seem to delete certain words from the text of my Document

Hello, good people. My issue is as stated in the title: I’m doing an analysis on the text of scraped Instagram posts that I’m later feeding to a Topic Extractor (LDA) node and then continue the analysis.

Problem is, I tried with a Stop Word Filter node, I tried adding a custom stop word list, I tried the Dictionary Tagger and Replacer nodes with a custom list, I tried lemmatizing before and after the nodes, but nothing… Some instances of the words I want to see deleted still remain in the text, and they later get picked up by the topic extractor node which creates many redundant words shared by multiple topics.

Here’s a snippet of the preprocessing (pardon me for the mess):

I’ve entered not only contractions such as “n’t” inside my list(s) but also full words like “cities”, and yet they’re still present in the output. I don’t know what to do at this point, other than doing a String Manipulation before turning the text into a Document? But that would be pre-lemmatization, so some occurrences could still be missed later on.

Here’s also the workflow alongside the data:
