1940 U.S. census index problem

in Search
Only six records appear to be indexed from this page of the 1940 U.S. census, and two of them appear to be duplicates of each other. (When you click on one entry for Fannie Crauford, it highlights both records.)

I think additional records may have been indexed from this page, but some sort of error is preventing them from appearing.
A similar error also appears more frequently on the 1930 U.S. census.
I wish there was a way to report these sorts of errors directly from the image viewer when some indexed records are missing.
