Level Check filter only allows you a max of 221 instead of the current new max level. Trying to enter any number higher than 221 obviously results in the value being registered as 0. Not sure if this is being worked on, but I searched it and it didn't show up so yeah :P

We have already been informed of this and will be taking care of it.
