What Behavior->Text Analyzer mode you are using? Is it simple or advanced?
- if simple - I would suggest to open Text Analyzer rule (Clipboard Viewer -> ChannelConfig -> pyFreeTextModel and find it in Records->Decision->TextAnalyzer) - then try to Action->Run on this Analyzer and put the example text there. Check the results.
- if advanced - Check if you have more than one Analyzer which could return Entities (for example two Pega NLP).
