What's Wrong?

have been using this for many hours, just recently ran into this bug, first off I see some of the RAG output that i'm not supposed to see in italics, slightly lighter text followed by the user visible summary, i also see a ton of "E"'s being printed which also looks like it shouldn't be user visible. hopefully this is not using up my output tokens.

What Should Happen?
