Adding new custom fields to a CMS and it doens't appear


I was working with a CMS collection and at a certain point I was dealing with an error.
At some point I was creating new custom fields, but once I tried to connect those fields with elements on the website they moved at the top left corner of the screen and they were not visible (see screenshot). Also, there are some text fields which used to work (they did show when connecting them to fields), but now when I try to make an adjustment, the adjustment is not visible.

Does anyone know how to fix this problem?

Kind regards.
