If you are interested in VBA, here I also can introduce a VBA code to solve this task.

1. Press Alt +F11 keys simultaneously to open Microsoft Visual Basic for Applications window.

2. Click Insert > Module, and paste below VBA to the new Module window.

VBA: Remove all duplicates but keep one.

Sub RemoveAllDeplicateButOne()
    Dim LR As Long: LR = Range("A" & Rows.Count).End(xlUp).Row
    ActiveSheet.Range("A1:A" & LR).RemoveDuplicates Columns:=1, Header:=Name
End Sub

3. Press F5 key or click Run to execute the VBA, and the duplicates in list in column A have been removed but keep one.

Tip: In the above VBA, A indicates the column A, and A1: A indicates the list range, you can change them as you need.
