Incorrect display of product cards in the mobile version

I can’t figure out what is the reason for the incorrect display of product cards in the mobile version, namely the choice of product parameters. It is displayed correctly on the desktop version. But it is incorrect on the tablet and mobile versions. I wrote in support of the plugin for variable products, but they sent it to you. Because when activating/ deactivating their plugin, the display does not change. What needs to be done to make the option selection button display correctly?
