Why does Gradeboook History no longer display all completions for a given course?

Recently I find that when I want to verify completion date, the gradebook history will not give me the entire list of completions, perhaps only giving the most recent 10 (out of nearly 400 completions!) So I have to download the student quiz report to find what I need, which is a very clunky way to do things, when I used to be able to scroll down and find exactly what I needed.

I went to Gradebook history and then chose to filter by a particular student (above).  Does that help?  Did that do the trick? I don't have as many completions to check for.  I am now curious.

This seems to be a browser specific problem.  When I access Gradebook history in Firefox, I also get a list of only about 10 entries.  When I access it using Chrome, the entire list populates correctly.
