Why does AI Agent return document text from source in a much larger font than the original?

Summary:
The Procurement Policy Advisor is returning responses with unusually large font sizes when I want to see the source. The same content appears in a much smaller font in the original document (which one I attached to the tools in the Agent), but when it is returned by the Agent, the text is significantly larger and the formatting does not seem to be preserved. I’m not sure what is causing this behavior. Has anyone experienced the same issue, or knows how to fix it?

I am attaching a screenshot showing the issue. The text is taken from a document where the font size is relatively small, but after being returned by the Procurement Policy Advisor, it appears much larger.
