Botanist Extraordinaire bugged

MR0D1045

i am unable to complete this challenge. i have already completed it more than 10 times already. 4 times in the last 2 hours. i Get no indicator when i complete 1 survivor healed in full state and nothing when the match ends. I even got blessed by a afk player getting hooked twice and i healed him to full state both times with the med kit and the perk active. And nothing i didnt get it then so i have no clue what i am doing wrong or if the challenge is bugged for me there is no other way i can i think of. I need help
