This is probably the stupidest question in Eorzea..

..but uh, why are there two separate gathering logs for each gathering class? Like my Botanist has a gold icon for one log, and a silver icon for another.. They each have different stuff, to an extent, but there's also a lot of overlap. (Such as crystal shards showing in both of them..)

At first I thought the silver one was just things I found myself, and the gold one was recommended items to harvest, but.. there's plenty of items in both logs I haven't found yet. So uh.. yeah.. I'm confused.

Edit: Oh.. I am dumb. One is primary hand and the other is off-hand, isn't it? Haha.. ha.. ha.. sigh.. I haven't slept in awhile, sue me.
