Add "Status" field to Lead Entry-Form

Hi,

How can I add the status field to the Lead entry form?
If I go to "customize" on the Lead form page, the screen shows me "Custom Entry Form" and the form name is "Custom Pop-up Customer Form". I found out that the "status" option was unchecked.
So I checked it and saved.

I went through the "Entry Forms" options, I saw that this form is assigned to Customers, Leads and Prospects ...
But the one preferred is the "Standard External Customer Form" - external - and it shows the status field.

But I don't want the Customer form to change only the Lead form..
