Fix awkward duplicate wording when deleting a data filter

When I tried to delete the default "DuplicateData" data filter, the attached error message appeared ("Are you sure you want to remove this array item array item?"), but it reads awkwardly because of the duplicated "array item". The 2nd "array item" and the bolding on the "this array item" are not needed. Alternatively, replace "this array item" with the ID of the data filter. The bolding of "this array item" suggests that this was supposed to be the case, and that the 2nd "array item" would be telling the user that the preceding text refers to an array item, but it seems that somebody forgot to replace this placeholder "this array item" text with a reference to the ID.

If this detail matters, I was trying to configure the AVEVA Adapter For RDBMS.
