Character Max Acceleration incosistent when changed via Blueprint

I have been trying to change the character movement settings during gameplay . For most settings this works , but when I change the “MaxAcceleration” It will not alt textbehave the same way when I change it back to the original value .

The images below show the current set up . The “MaxAcceleration” is set to 2048 in the character blueprint default settings . I can change this during game play via Blueprint , but when I change it back it will not behave the same as before .

I am experiencing similar issues here, increasing the acceleration via a blueprint in game throws the whole thing off, increasing it actually makes my character accelerate slower :S
