Why is my product size selector button larger than the rest?

Hi,

I have 3 products on my web the size selector button is too big than the others.

for some reason only this 3 products size selector button too big, all other products all good. I try to deleted this 3 products and add again, still have this issue. Also I try to add some other products and have no problems, don’t know what happen only this 3 got issue. Please see those 3 products link below, I also attached the screenshot.

Thanks

@X-DREAM - these products have invisible price options and hence they are big, have you added something like that?

I don’t think i add something like this, I add other products same way, but other products have no issue.

I think I know what happen, I changed all the variant to same price, this problem fixed. But I need different price for different variant, need solution for it.
