After exiting dropdown word doesn't go through "On-Exit" sub

[OGKro]

I have a dropdown list that says Yes and No. Theres also a macro linked to it "On-Exit" which is :

Sub Exit_DD_33()
'ASZ 04/2023
If ActiveDocument.FormFields("DD33").Result = "NON" Then Delete_Dropdown33
End Sub

Sub Delete_Dropdown33()
'ASZ 04/2023
ADMIN_unprotec
    ActiveDocument.Range(Start:=ActiveDocument.Bookmarks("StartDD33").Range.Start, End:=ActiveDocument.Bookmarks("EndDD33").Range.End).Select
    Selection.Delete
    ADMIN_protec
End Sub

For some reason it works for all the previous deletes but for this one it doesn't. Even tho it works when you go step by step. When just using tab after you chose No nothing happens.
