Yes, the initiative one is special; it is set to be a token action in the sheet's code. Mainly because to use it and get the value added directly to the initiative tracker, it has to be used with the character token selected. It was also the one macro out of all of them that I figured everyone would use regularly. :) If you want to re-set it to its original state, you can just go into the Attributes & Abilities tab and scroll down the Attributes side looking for "initmacro" and just delete it entirely. The sheet will recreate it the next time you open it. And yes, that is one of the common and easy ways to end up with a duplication like that. (Adding the character sheet template to campaigns that existed prior to implementation of the character sheet templates, which had the macros created previously is another common way to end up with duplicates.)
