Hi @khouloudbelguith

Thank you for creating this issue. I am not sure its severity should be this low (minor) because its not an isolated use-case: every merchant is concerned by this bug, and the reordering "feature" is very important for the merchants.

All our prestashop customers are impacted, and they are all hoping we can do something for them quickly :-(

@mickaelandrieu this is the products BO reordering issue we mentioned last week during your training session :-)

The problem is fixed if we use the icon in position column. The product is selected and we can change the position and saved and all changes is validated.

Since this PR correct the problem it's OK a New issue was created for the second issue : #15291
