Two different boards???

So I made post about Gandalf and bard, and left this board, then I did come pack and boards were different in this board there is more categories and Miscellaneous board but in another there is no Miscellaneous and less categories both of them are in same country (EU NORDIC & EAST) but when i go through lol site it brings me to boards where is less categories and no Miscellaneous and show i never made any posts. but if you google "lol bard gandalf" you can find post what i made into this board and tells I made this post in my account but doesn't tell about posts what i made to the another board.

I dont understand anything, is there 2 different versions of boards? help.
