Magento 2 cache files and generated files keep chanching ownership

I have created a superuser and set my project owner and group to be magneto www-data . I’ve set the folders and file permissions using the commands below.
I followed the documentation from Magento

• https://devdocs.magento.com/guides/v2.4/config-guide/prod/prod_file-sys-perms.html#mage-owner-two-prod

But for some reason the files inside my cache folder and genreated folder keeps changing ownership.

find . -type d -exec chmod 755 {} ; && find . -type f -exec chmod 644 {} ; && chmod u+x bin/magento

find var generated pub/static pub/media app/etc -type f -exec chmod g+w {} + && find var generated pub/static pub/media app/etc -type d -exec chmod g+ws {} + && chown -R :www-data . && chmod u+x bin/magento

I found a person with thesame issue but without any resolution:
