This is highly unusual - a product with significant deal volume but zero conversions. I need to verify this is truly GTXPro (not a typo/variant of 'GTX Pro') and understand if there's a data quality issue or a real business phenomenon. Let me search for GTXPro specifically to see actual row data.",
