Unable to edit a footnote concerning Randolph Thomas Edwards aka Thomas R Edwards edit

I am unable to edit a footnote concerning Randolph Thomas Edwards aka Thomas R Edwards. It reads "Thomas Randolph Edwards received a Bachelor of Philosophy degree in 1879. He died at Central Lake, Michigan, March 5, 1922, age 61."

It would more accurately read.

"Randolph Thomas Edwards, known as Thomas R Edwards at the University of Michigan, received a Bachelor of Philosophy degree in 1879. He died in Central Lake Township, Antrim Co, Michigan, March 5, 1922, age 65."

Note: death age. He was born 29 Dec 1856, in Ann Arbor, and graduated at age 22, not 18. His birth year is documented in the 1860 census. This and other records can be seen here. </ref>http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=rtegen&id=I00003</ref>. He is my grandfather. I find it strange that the death date is correct while the implied birth year is wrong, since the only possible source is my genealogy file, his death date appears accurately nowhere else. His death date is entered in the Antrim County records under the name Richard Edwards, perhaps a guess based on his initials RT, by which name he was generally known.

When I attempt to edit the references, all I see is this:

Hi, I made the change you requested. Of course, we are very interested in any information you may have concerning your grandfather and his life after the University of Michigan. Also, if you have any photographs of your grandfather that you would be prepared to upload, I would be happy to assist. You can leave a note for me here or at my talk page. Thanks.
