Yeah that’s definitely poor quality control. Looks like a foot fell off at the factory, and someone @ Teclast towers stuck the nearest they could find to replace it… (because you’re aware that Teclast don’t actually manufacture their own kit, they submit design specs to factories that also make hundreds of other brands like Jumper etc which is why they’re all so similar).
Anyhow I digress… Yes, any sticky-backed rubber feet will be compatible. You’d just peel off the four existing ones and replace with your new chosen ones. The ebay link I showed in your PM (because the site wouldn’t allow me to post in here) has many different sizes and you can choose whatever looks/feels right for your use. If you’re not sure, just measure the existing feet and order the nearest size.
