Cyclist's Corner review for Kiwi Size Chart & Recommender

Install recently. Very confusing to configure, few tutorial videos. I saw in a store how they configured it, I liked it, so I installed it. But I was able to do a part alone, the SIZE CALCULATOR part does not appear to me nor does it appear in INCHES. Support sometimes responds and doesn't solve anything. They always ask me the same thing, I answer them, I send images, a link to a Store showing what I need and they explain it to me and no solution so far
