AI Field Builder: Issue with Industry Field Picklist Matching

Issue: When using Clay’s AI field builder to match values from the “Industry” field against a custom list of picklist values in the prompt (via Enriched Industry), the AI occasionally returns results outside of the allowed picklist list. Example: “Advertising Services” is returned, even though that option is not in the defined list provided in the prompt. Expected Behavior: The AI should return only the closest exact match from the list provided — no free-text or unlisted values. Question: Is this a known quirk or limitation? Are there recommended workarounds to strictly enforce selection from a defined list?
