Reckless Assault seems to be suppressing itself because i tried to toggle it. I removed all my gear and equipped unenchanted weapons with no modifers that effected accuracy, deflection or +damage as well as deactivated my other modal ability without the Suppression effect disappearing.
I loaded a much earlier save and the suppresion was not in effect, but i could force it to be suppressed by trying to toggle Reckless Assault off. However, when I tried to reactivate the modal ability the suppression would not go away. i was even able to get it to list each effect suppressed twice at one
