Reply To: Page anchor not found

I am using CC 2015. One of the fixes I tried was to update the software. I just downloaded the latest version of ID and still have the same problem. I think I might have found a clue though. I discovered in the ePub with the errors that wherever there is a page range for an index entry (66-67, rather than just 66), clicking on the first page in the range (66) is a working link but clicking on the second page (67) is not. Out of curiosity I counted how many entries in the index list a page range. Right around 200. I will be editing those in the index panel to see if that fixes the issue. Unless there is a way to tell InDesign to generate an index with only the first page in a range?
