wrong whatsapp number

Hi ! I want to buy your premium version but I have a problem on the free version. I use a WordPress site and I use Polylang for a French / Spanish / English translation. To carry out tests at the very beginning, I used an “A” number. When I made all the settings, I changed the number to put a “B” number. My problem is that the “B” number (the one I want to use) has been taken into account on the French version of the site. On the other hand, if I change the language to English or Spanish, it is always the number “A”. I tried uninstalling and reinstalling the app. I also tried to clear the cache but I still have the same problem. Could you help me please ?
