Hi,
The message "Der In den Warenkorb Knopf erscheint sobald die obigen Werte ausgewählt wurden" is displayed by HikaShop when a product has characteristics (e.g. size, color) assigned to it. Even if no actual variant products have been created, the presence of characteristics on the product triggers this behavior.
Please check the product configuration in the backend:
1. Go to Products > edit the "BleeqUp Ranger" product
2. Look for the "Characteristics" section/tab
3. If there are any characteristics assigned, remove them since this product doesn't need variants
If you don't see characteristics but the message still appears, please check if you have a view override for the product page. Go to Display > Views and look for overrides of `product/show_default` or `product/show_block_characteristic`. An outdated override from a previous HikaShop version could cause this.
Also, I would recommend updating to HikaShop 6.4.0 as there have been many improvements and fixes since 6.3.0.
