NPrinting Error with an existing Excel Report

[senior_freshmen]

Hello,

today i wanted to edit an existing Report in Qlikview.

I did insert a new label for a table in the Report, which is an excel sheet.

But it was a false statement and the message "Error in statement" occured. But somehow im not able to delete the false statement, when i try to open the sheet in the Report Overview i see nothing and i cant edit anything.

How can i edit this sheet now?

Update: Its not only the Project with the false statement which i cant edit.
Now and i dont know why i am unably to edit ANY projec in NPrinting.
