Cant collect herbs

I learned alchemy, I learned herbalism, i have a shovel, and the oil thing. I try press the space bar(yes I checked that the space bar was the harvest key, it is) and it wont let me harvest any herbs. It just spams "You cannot collect it yet" in the chat window. My fatigue is at 0 because i havent been able to harvest any herbs at all.

Can anyone tell me what the problem is or what im doing wrong? I tried unlearning and relearning it and the same thing happens.
