Issues Displaying Labels in Posts

Hello, developers.

I have an issue when displaying the posts. The corresponding labels for the fields are missing. My page is a recycling exchange platform where users can enter various fields such as material, phone number, location, and what material they wish to exchange. These fields are requested when posting, but when the post is displayed, only the fields are shown without their labels. You can see this in the links to my page:
