extra slots showing while upgrading

We have been having a huge issue while upgrading to lvl 2, we have a full guild and as we have been upgrading it shows the extra 10 slots. we have been having people screaming at us because it shows us having 60 slots when we can only hold 50 until the upgrading is finished. we are in the thor server and XILE Guild. this has been a huge headache. Can you please fix this before other Guilds have this issue....Xile, XILE2, Mongols all are full and Xile2 and Mongols are close to having the same issue
