Default [Q] Lenovo A820 (bigpart/meteos) trouble

Hi,

i recently changed the partition on my A820 using the meteos utility to 2,5gb data. Looking at the storage pane in the settings it says the following:

internal storage (~5% used)
total storage space: 2,46gb
available: 2,34gb


Phone storage~10% used)
total storage space: 273mb

SD-card (~20% used)
available: 6,08gb

Problem is, whenever i try to install the game "Blitz Brigade" from play store, it keeps complaining that i'm out of storage space (which i shouldn't be). I did set the installLocation to SD-card (same result) and even ran the Meteos tool again + recovery + factory reset. Same problem remain.

I tried the "Storage Analyzer" app in play store and got the following

/storage/sdcard0 : 273mib total / 238mib free
/storage/sdcard1 : 7,39gib total / 6,08gib free
/system : 590mib total / 94,5mib free
/data : 2,46 gib total / 2,33gib free

and also entries for /cd-rom, /protect_f and /protect_s

Could it be my partitioning that went wrong or is it just Blitz Factory that insists on installing in the wrong partition (i.e not adjusting to the preferences in the storage section?)
