Weakness potions

well this bug is for devices however i cant include them all . lets get into it : Drinking weekness potion creative mode was it or survival is the same. you cant hit mobs or any entity even a player by hand for the hole game even if the effect was gone you have to drink strength potion to make it be back again but as soon the strength goes the old effect will come back but il not show just like its normal but not causing the player to get angry that he made hole survival world but cant hit entity ive tried it on pc its not like this , thanks for all hard working
