unremovable '(blank)s' in Pivot table

The word (blank) appears in a pivot of mine, although I've used 'Table options' -> 'for empty cells, show:' and selected the blank field.
Could it be the Greek version of Windows? However, I tried to correct this problem through an English version computer, but it persists.

Some help please?

Dear friend,

thank you very much for replying. However, your answer didn't help me, partially because I think I didn't understand you and partially because I think you didn't understand me or I was not clear enough.

You mention the drop downs. But I'm talking about the data field. Please see attachment. In my own computer, with the english version and where I'm now, there is no problem with this (the attachment is deliberate) but with my job's PC, with the greek version, I cannot remove these ...stupid (empty)s! ... and my manager, who reads the report, complains! (with his own right, understand me ? : ( I tried to remove it by editing the file in an english version PC, but the problem persists.

What I've thought of right now is to make a conditional formatting with white font color wherever "(empty)" appears. Do you have any other idea though?


Thank you for your interest and all the best too
