ChatGPT Ignored a Stored Preference for Canonical URLs

I found what appears to be a consistency bug in ChatGPT's memory/preference system. I repeatedly instructed ChatGPT not to provide URLs containing ChatGPT tracking parameters such as:?utm_source=chatgpt.com I specifically requested canonical URLs without tracking parameters because I frequently work with NRC regulatory documents and need clean links for documentation purposes. The preference was acknowledged and later d in memory.
