Bug adding product to cart

I have a landing page with a “choose your plan” section which contains two different product. I’ve found a bug for a week that the two buttons has the same product. However, when I’m editing in Elementor my landing, each button has linked different product but when I preview/publish it, the second button has the same id the first one.

I’ve installed the last version to the plugin (2.5.5.). My theme is hello, but I changed it, and the problem persist. I don’t understand what happen, could you help me?
