Le bot 7.6 Xp boost glitched on me

[Delacroix21]

Title explains most if my problem; I stated playing AQW again and wanting to test out Le bot function but after getting a free bank space and clicking on get Xp boost or any from the option menu it says " You need at least 1 free bank space" However if I send the spammer code it allows me to get the item except the xp boost. I also went on the real server with one of the other boost and sold it/dropped it but it didn't work. I tried re downloading Le bot again but no avail and I tried goggling the problem but nothing came up. Any help would be appreciated! I attached an image of the problem on the bottom; waiting for approval.
