Different kinds of Hextech Chests or just max Stack?

In my Loot Tab, there Hextech Chests are split into 2 stacks... Are there any different kind of Chests or is the stack limit just 30? Also, 32 chests because ive not been able to reach honor 2 in spite of being on the 2nd checkpoint of lvl 0 since the rework came out. thx riot screen: http://prntscr.com/ibin8r
