why CTRL SHIFT ENTER in my excel does not give braces { }?

Hello,
In my file I have that formula

=IF((COUNT(IF(H839:H914="D",ROW(839:914))))>0,"D.",IF((COUNT(IF(H839:H914=11,ROW(839:914))))>0,"11.",IF((COUNT(IF(H839:H914=10,ROW(839:914))))>0,"10.",IF((COUNT(IF(H839:H914=9,ROW(839:914))))>0,"9.",IF((COUNT(IF(H839:H914=8,ROW(839:914))))>0,"8.",IF((COUNT(IF(H839:H914=7,ROW(839:914))))>0,"7.",IF((COUNT(IF(H839:H914=6,ROW(839:914))))>0,"6.",IF((COUNT(IF(H839:H914=5,ROW(839:914))))>0,"5.",IF((COUNT(IF(H839:H914=4,ROW(839:914))))>0,"4.",IF((COUNT(IF(H839:H914=3,ROW(839:914))))>0,"3.",IF((COUNT(IF(H839:H914=2,ROW(839:914))))>0,"2.",IF((COUNT(IF(H839:H914=1,ROW(839:914))))>0,"1.",""))))))))))))


that requires CTRL SHIFT ENTER in order to work properly.
The point is that when I press that combination I do not have the curly braces { }.
If I paste that formula to ananother empty xls and press CTRL SHIFT ENTER - curly braces { } appear.

What could be the reason for that?

Thanks!

When i mark onto the cell formula is there but there is no curly braces

In the cell i have the result of the formula. (eventhough the curly braces are not there). The point is that after some time when i open the file the efect of ctrl shift enter has gone.then i have to do the cntrl shift enter again. Curly braces are not there but the formula result iscorrect in the cell.
