The WeChat card and coupon shelf shows that it has been received

After creating the coupon, I created the card and coupon shelf based on the card_id. However, when I click the return link to enter the card and coupon shelf, it is displayed as shown in the figure. It is received every time. What is the reason? (I am sure that I am the only one who received the link. I did not do any receiving operations before opening the link. The official account is a test account, the personal account has been added to the whitelist, and the coupons are not customized)

Send data as follows:

<code>$shelvesData = array(
    "banner" => $url,
    "page_title" => urlencode("优惠"),
    "can_share" => true,
    "scene" => "SCENE_H5",
    "card_list" => $card_list
);</code>

When I clicked on the coupon (not the button):
