Item Collector

[superhorst90]

How to collect all items? I’m at 84% and don’t know how to get the last 16% and where to get it. 
I got all the 5 items from shenlong, finished the story mode so got all items there aswell and also got all the items from the tournament mode. Yes I won on every difficulty at least 5 times and of course I did the 8 player and 16 player tournament. 
 

I just don’t know what to do and where to get the last objectives. Also every guide I came around said that I just have to finish story mode, 5 shelling items and the items in the tournament. But this isn’t enough. There has to be some other items but I don’t know where. Please need some help.
