erros sold out

inside any product on my website that has a size variation, before there was a little line on top of the one that was out of stock and when I clicked on it, it said ‘out of stock’, but now when I open a product, at first, it appears that all sizes are available, I need to click one by one to know what is or is not in stock. So, when you know which one is out of stock, a pop up opens informing you that it is not available. a bad experience, the customer needs to take a look and see what he has or not, and not need to keep clicking one by one to know what he doesn’t have.

if you see it on my website, it has three rows of variation. because I had to put a plugin to try to solve it. but it is giving error, it creates two variation lines by itself and the woocommerce native variation is the third line,

2) another point, how do I delete this “dropdown” that appears saying it’s in stock when I click on a size variation? I wouldn’t want that, I just want the customer to click on the variation, nothing else needs to appear.
