That number is unit price (price per 100g) feature. It’s pulling the wrong reference unit, which is why it looks insanely high.
Fix it by editing the product → Pricing → make sure the Unit price measurement is set correctly (e.g., 240g total, reference unit = 100g), or simply turn off unit pricing if you don’t need it.
If you want, I can guide you quickly on the exact setting to change so it displays correctly.
