The national public institutions recruitment system does not have a supplementary upload button

System bug. Many people do not have the supplementary upload button in the national public institutions recruitment system because there is a bug in the recruitment system, which causes the supplementary upload button to get stuck and disappear. As of September 19, 2022, the system bug has been officially fixed, and users only need to add the supplementary upload button. The problem of no buttons can be solved by closing and reopening the recruitment system page.
