Update product prices with incorrect prices

[ikran]

Good morning,
I have an e-commerce in Prestashop and I have updated the prices of all the products with the new 2023 price lists, there are around 5000 products.

To do this I used the Prestashop integrated procedure, I went to the products bak-end, I clicked import -> products and I chose my file properly formatted with the product id and price excluding taxes.

The procedure was successful and I have the products with the updated prices.

For some products, however, the correctly updated price excluding taxes is displayed in the front-end, but for the price including taxes, the price without taxes is always displayed.
If I go to the back-end, search for the product in question and without making any changes I click on save, the price is displayed correctly in the front-end with taxes excluded and with taxes included.

Did I do something wrong with the import?

Hello,
I guess that with the import, the calculations for the tax-included values weren't triggered for these products, or something is missing from the import document (like, an example, the Tax Rule ID). 
This calculation is called when you hit the save button on the product edit page and resolves this price issue. 
You can try to check what happened in the /var/log files or in the server log if this issue appears only for some products. 
Also, you can try to import the values again only for one product where this issue appears to see if it imports now correctly. 
I hope that I could help.
Have a nice day, Leo.
