Customizing the interface in a task

Hello! In the task https://topbox.1b.app/14298/ in the interface settings of the products table, the function of mandatory filling in the additional field of the product "Laying patterns fri" is selected. This field is filled, but when you go to the "Test" stage, it gives an error, it says that the given field "Pattern layout Fri" is not filled, and accordingly does not skip to the stage. The additional field of the product "Pattern layout fri" was filled directly in the task, before that it was empty. You can try the test task with it.
