You are not allowed to use {block}

Ok, so I noticed in the code for handling disallowed blocks that it had a check for admin.
The codes reads:

if (actor instanceof Player && worldEdit.getConfiguration().disallowedBlocks.contains(blockId) && !WorldEditHandler.isSuperAdmin((Player) actor)) { throw new DisallowedUsageException("You are not allowed to use '" + input + "'"); }

However, the check for admin does not work, and blocks the block for ALL players including staff.
