Should be Bethlehem, New York, but indexed as Maryland.
You are right.

@Mirevo, the collection title is not editable, and it says Maryland there, too. See for example https://www.familysearch.org/ark:/61903/1:1:QGK6-326D, which is the first index entry from the image that Alan linked. It is clearly labeled at the top of the page as "Reformed Church, Bethlehem Twp, Albany, New York".
Basically, the index entries for these images have been put in the wrong collection. Some of the pages have had the marriage place corrected, so they look OK on the index tab of the image viewer, but if you go to an index entry, it still says "Maryland, Church Records" in the collection title. (For example: https://www.familysearch.org/ark:/61903/1:1:QGLJ-MMH6.)
