The Error filter doesn't filter all tag discrepancies
Context: You ran the Error filter on a document in memoQ and realized that some tag discrepancies are left unfiltered (where "Blue Tags" are missing in the target text for instance).
Description: The Error filter's purpose is to find and display tag discrepancies that would prevent you from exporting the document. Luckily most tag discrepancies are not so serious and are only warnings. As a result, they do not show up in the Error filter.
