Acrolinx plug-ins usually highlight the issue text in the document and help you navigate to the next or previous issue by scrolling the document for you. Due to API limitations of Lotus Notes, Acrolinx is not able to highlight the active flag in the document. This limitation makes it difficult for you to see the issue in the context of the original document.
To overcome this limitation, use the issue text field in the corrections dialog to view the sentence which contains the issue, and directly edit the flagged text. If you need to see the full paragraph to know what changes to make, then you'll have to look for the location of the issue in the document yourself.
