Small Locker Bug

After getting the third guild upgrade and having three items in the three locker slots before, they got cloned into the other empty locker slots upon relog.
Meaning I had a guild hall lvl 2 with three items in the three locker slots.
After I upgraded the hall to lvl 3 I had 6 locker slots, in three of those were the old items from before. The other three were empty like they should. After I relogged the three items had suddenly duplicated into the empty locker slots meaning I had 2 of each of the original items.
