Unless your ancestors died in a cemetery, then that is not a valid death location, and as you have a fair number of suggestions with that problem I'm guessing this is the issue. Cemeteries are burial locations, not a place of death.
Asa Benoit is shown as having died in Saint Anthony Catholic Church Cemetery, Lake Arthur, Jefferson Davis, Louisiana, United States, but of course, he did not die in the cemetery, he is simply buried there. Now, someone might think the easy fix is to just remove the cemetery name, but that would still be wrong because his obituary states that Mr. Benoit died in the Jennings American Legion Hospital which is in Jennings, Louisiana, not Lake Arthur.
If you want to make note of the burial place, it should be done in the biography, not in the death location field. Sometimes people are buried 100s or even 1000s of miles from where they died. My great grandmother died in Detroit, Michigan, but she is buried in Spartanburg, South Carolina. If I used her burial place in the death location, someone looking for a death record would be hard-pressed to find it.
Hope that helps explain some of the problems with using burial info in the death field.
