Edit single in-text citation without updating the whole document


I am trying to edit a single in-text citation to change the formate from (author, year) to author (year). I am following the tutorial in the following link:


However, every time I try to do this for a single citation, Endnote is updating the whole document in-text citation and bibliography. This takes too long time since the number of pages and references are very big. The instant formatting is already turned off.

Any idea how I can do that without updating the whole document?  I am using Endnote x7.5 with MS Office 2016

Best regards
