Delete imported field

Hi There,

Is there a way to delete a field, for example “age”, I imported earlier via simple CSV?

To be perfectly clear, a few weeks ago I imported some users and userdata like this:

Email; First Name; Last Name; Age
[email protected]; John; Doe; 32
[email protected]; Mary; Doe; 24
[email protected]; Johnny; Doe; 27

I did this for a client, who now doesn’t want the “Age” field to appear in every user statistic.

Is there a way to delete this custom field?

Thank you very much,
Kim
