Export Customizations Is not Working

Good Day Community

I´m trying to export several custom fields using the “Export Customizations” option but when i install the package in my production instance only the labels are created but no the fields.

For example, I created a field named “Brands” and the label is LBL_BRANDS in a Sandbox instance and when exported to Production only appears created the label but not the field, and in the layout only appears the name of the label LBL_BRANDS so I understand that the relation is working correctly but only the field is missing.

Do you have any suggestions as to what I might be doing wrong?
