Hello @usmanyousaf112,
thank you for posting. This is basically a Low Pricing error. This indicates that the particular product was sold for a much lower price than how your offer is currently priced, at some point in the past.
If you go to Pricing - Manage Pricing, you will be able to review any pricing alerts and set your minimum and maximum price to prevent having your offers deactivated over this.
If nothing works, keep increasing the price until the listing stays active.
