Find the bug causing post_meta values to disappear

Hello, I have a backend which enables the administrator to fill in usernames (card numbers) and their points and place in each event (post_type). This "works" with the help of tickets being stored in the database, along with the total number of points and place.

A very experienced freelancer worked on this before, but apparently left a bug that causes some users to disappear from the backend (from a single event), and that causes errors in total points.

In the screenshot, you can see the gaps between the value "Místo" (place). There were all numbers from 0 to 24, but now there are some missing (red numbers beside the column). That is the problem.

So, please only sign up if you're confident enough with English, Wordpress and are able to read and understand the code of somebody else. I'm able to pay $60 if you can find the bug and fix this. $30 before, $30 after.

Habilidades: Programação de Banco de Dados, MySQL, PHP, WordPress
