Problem with field names

The donation form show fields for donors to fill in their information, but show no labels. please see attached screenshot.
Thank You   

Hi Alberto,
You should open tool: Custom Fields at Backend of Joom Donation and open all existing custom fields to modify. In Field management form, please open tab: Translation and enter the title for fields in different languages to solve this kind of issue
Thanks

All the fields are already listed and they are not missing. Also if you see the photo some of the fields are showing and others are not. 

Hi Alberto,
Please read my comment carefully, i mentioned to tool: "Custom Fields" at Backend of Joom Donation, not "Translation"
Thanks
