Maybe you are too low of Summoner Level ?
Not sure what Level you have to be to hold 4x of Tier-5 Basic in INVENTORY.
Rest of them go to STASH Overflow Reserve, which can NOT be used right away.
You might need to be Summoner Level 50 ? (or 55, or 60 ??) in order to store enough of them in Inventory (not Stash), and be able to upgrade 6* to Rank-3.
