The 'extra' redaction is caused by the misaligned page break. The items that need to be redacted are redacted.
Pre-version eDP 10, the near native view was converted using a pixel representation of the item. When a page break was encountered, the data text string could be split between two pages (See Figure 1).
Figure 1

In eDP 10, PrizmDoc is used for the conversion to near native view. PrizmDoc utilizes a PDF format which allows for a hard page break, thus eliminating the splitting of text data between pages (See Figure 2).

To no longer see the 'extra redactions', upgrade to eDiscovery Platform version 10.
