Unrecognized Fields

[GatorBandAlumni]

In effort to clean up our contact list, I exported an Excel sheet inclusive of the custom fields we created. Upon opening the file, I saw that we had multiple home numbers, multiple home addresses, etc for several contacts. These are NOT any of our custom fields. I did not change the names of the fields but I did try to consolidate them.

For example:

First Name: Jane

Last Name: Doe

Phone - home 1: 555-555-5555

Phone - home 2: blank (NOT A CUSTOM FIELD)

Phone - home 3: 333-333-3333 (NOT A CUSTOM FIELD)

I cleaned it up to be:

First Name: Jane

Last Name: Doe

Phone - home 1: 555-555-5555

Phone - home 2: 333-333-3333 (NOT A CUSTOM FIELD)

Phone - home 3:  DELETED COLUMN

Even though 'Phone - home 2' was in the Excel sheet I exported, when I try to import the cleaned up version of the file, it won't recognize 'Phone - home 2' as an existing field. And even if I wanted to create custom fields to collect the second phone number, I cannot delete the existing 'Phone - home 2'.

What I exported is below. The yellow fields are not custom fields.

What is happening when I try to import the same file.

I don't want to lose any of the data we've collected, but I also don't want to be stuck having the same address show up under a contact 2+ times. Please help.
