Unkown different discount applied on pdp and plp

[front7]

Description: I am experiencing an issue with PrestaShop 1.7.6.7 in a multistore configuration. On one of the stores, the discount applied is not displaying correctly on the production page.

Details:

• PrestaShop Version: 1.7.6.7
• Configuration: Multistore
• Issue: The discount added in the back office and checked in phpMyAdmin (table pssties_specific_price) shows the correct applied discount of 21.88. However, on the production page, it shows 34.8. This incorrect discount was tracked but could not be found anywhere in the system.

Expected Behavior: The discount displayed on the production page should match the discount added in the back office and checked in phpMyAdmin.

Actual Behavior: The discount displayed on the production page is 34.8 instead of the correct 21.88.

Additional Information:

This issue is occurring frequently I have 17 shops attached but I appears on one or two after updating,
To solve I delete all discounts on the table related to shop id and upload the discounts using the import

The incorrect discount was tracked but could not be found anywhere in the system.
