@Joel Weiner, I am sorry that you are having difficulties with this collection. This is a problem that has previously been reported to our engineers. They are aware of the problem and are looking at it. Unfortunately, I cannot suggest when the problem might be fixed.
The problem affect three of the Massachusetts collections: Massachusetts Births, 1841-1915 (as you've noted); Massachusetts Marriages, 1841-1915; and, Massachusetts Deaths, 1841-1915.
With you, I look forward to seeing these problem collections corrected.
