Taking damage then practics with wooden mace

This is very strange and im getting bit mad on it…

Then i pratics with axe/sword/haldbard I take no damage what so ever…

But as soon is wooden mace. I lose health and start to bleed… Now this most cleary be a bug and if you say is because is a wodden club then look at the halbard which is just a wooden staff and aaxe with a cleave form which also could cause damage.

If this is part of game then… well it sucks XD
