Cant hit skillchecks when using a common medkit

MissBehavingX

It hasn't happened with other kinds of medkits, maybe i have just been lucky but today I had 2 games where my skillchecks wouldnt register while healing with a common medkit. It only happened when I used the medkit, if it was CoH it was fine, I thought it was a one time thing but it happened again like 2 matches after that one. I'm on PC
