Hey Leanne,
I am guessing that is the most likely answer. Although, according to my research, the online version should have never had access to all of the different citation styles, so in general that is just very confusing. I kind of just discovered endnote becauce of web of science and was like “Oh hey, this is convienet, I will just use this”.
Unfortunately, I am not at that institution anymore, although as an alumni I still get accesss to Web of Science, etc. Anyway, I will look into getting the desktop version. Thanks for the reply!
