ok, if you meant that your character wasn't blocking the move, then it is a big bug !
probably due to the all mighty BLOCK BUG that many seems to have ! which makes you character not being able to block some moves !

otherwise, if you were meaning that you were blocking but your charcaters does get damage anyway... (a little less then usual) then this is what we call CHEAP DAMAGE !

example: (based on real life)
if i punch you hard and you block but putting both of your hands in front of your face... will it not hurt a bit ?

thus this is CHEAP DAMAGE... even if you block, you get damaged, (damage being reduced by 1/2 or 3/4 depending on the move) so all you have to do is block, then superjump. by blockiung the opponent is suppose to be pushed backward after the 3 hit ! that will be your time to superjump out of the way ! or throw in an helper + super ! which is accurate too !
