Selected items aren’t added to the order after

When I select items to add them to the order in WooCommerce, they aren’t added to the order as expected. My actions are as following.

1. Click the button ‘New order’ to start a new order.
2. Click the button ‘Add items’, then ‘Add products’.
A pop-up window appears for item selection.
3. In the pop-up window, select the needed products and quantities.
4. Click the button ‘Add’.

At this point, the pop-up disappears and I get an empty order window with a sandglass that keeps on spinning eternally.

However, when I click the ‘Create’ button, the order is created with the selected items on it. Still, to the right of each line, there seems to be room for an image but this image doesn’t show. Only a placeholder is visible.

Earlier, the items would be shown on the order and I could calculate the tax value before actually creating/saving the order.

Clearly, this behaviour changed after an update or a new plugin. However, I can’t pinpoint the true cause.

In summary,
– How can I see the selected items on my order before actually creating the order?
– How can I see the product images on the WooCommerce table?

Kind regards,
