Manually Edited Citations no longer update

Hi, I am using version Mendeley 1.9.2, and I manually edited references because the style was automatically, [1],[2],[5] but I needed it to be [1,2,5]. Now I have updated my entire thesis, and the mendeley software cannot update any of the manually updated fields. Is there a way to fix this without going to my old document and copying and pasting each [1],[2],[5] instance? Thanks
