Screenshot: The user fields does NOT appear on checkout

Hello,

I was considering buying the Pro version… but it seems that even the Free version is broken.

I have a fresh install (less than 24 hours) of WordPRess 6.4.2 with woocommerce 8.4.0 and SHOP AS CLIENT free plugin version 3.1.

The checkout page as yu can see here does not display the fields.

Informations on my store :

• Does Not do sipping, so only the Billing adress is required
• Use HPOS (but WITHOUT compatibility mode)

Can anyone reproduce this ?

The page I need help with: [log in to see the link]
