Maximum number of staff is not wroking
Setting a maximum number of staff for a specific task does not work as expected. It doesn't prevent people from registering for this task once the maximum number of volunteers is reached.
Indeed the color goes from green to blue when the maximum number is reached. And hovering over the count does indicate that this task is full but one can still register for this task and it makes the counter increase by one and go green again.
I'd be really glad if the amazing GNU IT Support team could have a look at it :D
