K55 Macro Trouble

[treelo991jr]

So i have had the k55 RGB keyboard for awhile now, i got this keyboard and some other stuff a couple years back to get into PC Gaming, and after sometime. I noticed that there was a macro set on the g1 key, No problem right, so i went into ICue and noticed that there was nothing set on it. I didnt really think much of it, now like 3 years later im on a different pc now, using the same keyboard and that same macro is still set on there, and only is there when icue is not running. I have never seen anything like this before and I could not find anything online, Im already looking into getting another keyboard, but it just stumps me as to why there is a macro set on that key even though there isnt? 

If anyone else can think why that is that would be awesome! like I said this has been stumping me now for a couple years!
