Assigned Custom Field Names not showing on report

For employee card files, I have created a custom report to show Name, Address, Phone, Email, Notes, Emergency Contact Name, and Emergency Contact Details.

I created the Emergency Contact Name, and Emergency Contact Details fields by going into Lists > Custom Lists and Field Names > Employees  (see screenshot below)

These field names are visible on the employee cards as below:

However, when I create my custom report (Reports > Index to Reports > Card > Card List [Detail] > Card Type [Employee] and then want to show \ hide the required fields, it still shows as "Custom Field 1" etc:

and so when I run the report, it comes out as below.

Also, does anyone know how to delete the default report name i.e. Card List [Detail]....  I've tried, but couldn't so I just moved it about the page.

I can export this report to .pdf, but can't export it to excel (the option is greyed out) otherwise I could have done a find and replace for those field names.

I had hoped to give each employee a copy so that they could check and update their details.

My workaround for now has just been to tell them what the custom field name is for if the details aren't recorded.

Thanks and regards,
