Bookmark Issue

When I attempt to update an existing bookmark, a window pops up and I get the following message: "Object reference not set to an instance of an object." Had the same thing yesterday and I started to post this, but when I checked to see if I could update another previous bookmark there were no issues.

Same thing today, though. Trying to update where I am reading results in the above message with no updating of my bookmark. I can go to another bookmark, advance a chapter and update my bookmark just fine, just not where I am currently reading, which is early in 3 Nephi.

I thought the last update had resolved this issue, but it's back at it again. Has been for the past few days. Version is 2.0.2.50.
