Invalid Switch - +Event+_#

The Preset Sync window will(Most of the time) have the lines:
Invalid switch - +Event+_#
(Where # is number, there's a lot of lines)

Is that a glitch in Preset Sync?

It seems that the Preset Sync is blocking most odd symbols. Keyboard layouts can vary and sometimes (as it seems) users might have issues due to special symbols. This username must be changed or otherwise players using the sync will not be able to see the preset.
