Not exporting custom data field

Hi Team,

Just want to say this first that this is an awesome plugin and works very smoothly.

However, there is this one problem we are facing i.e when are we trying to export our users we are not getting the “Phone Number” information, neither to map and nor is exported in the CSV.

Phone Number is a custom field we added ourselves on our WordPress registration form, validated and saved the data.

Exporting this phone number data with the rest is very important for us.
Could you please help?

Thanks
