Frozen Chest doesn't give item according to level

is it normal?

i'm level 36 but frozen chests always give me lvl 35 inventories excluding tokens ofc...

thank you...

The chests are broken into 5 level intervals except the ones at the end levels

level 10 - 14 will yield level 10 items
level 15 - 19 will yield level 15 items
level 20 - 24 will yield level 20 items
level 25 - 29 will yield level 25 items
level 30 - 34 will yield level 30 items
level 35 - will yield level 35 items
level 36 - will yield level 35 and 36 items
