Problem with products urls

Hi,
I have a problem with the urls of my store.
I have been using rank math for several months without any problem and I haven’t touched the settings since the installation, and since a few days I have a problem with the product urls:

I set the product url to be the following:
https://domain-name/product-name

But today when I place the cursor on a product, the url displayed at the bottom of the screen is the following:
https://domain-name/product/product-name

When I click on it to go to my product page the url is correct:
https://domain-name/product-name

My product sitemap shows the url https://domain-name/product-name

In rank math settings, I see that the option “Remove the base” is enabled for woocommerce products.
If I deactivate this option, my sitemap is well updated to the URL structure https://domain-name/product/product-name
But by reactivating the option my site map stays with this URL structure (https://domain-name/product/product-name) and impossible to go back to https://domain-name/product-name.

I tried to uninstall rank math and to reinstall it but nothing works. I tried on another shop which has exactly the same settings and I do not have this problem

I hope my explanation is clear enough

Thanks in advance for your help
