Tasks appearing on the wrong day

A lot of birthday reminders have all appeared under today's date. The fact that they are all bday reminders and under the same role is the only pattern I see. Do I have to go through each of them and reset? That would be really annoying.

I will use this post to also mention that there have been a lot of bugs lately, especially with the recurring tasks and it affected my trust in your product. If things do not improve considerably soon, I will have to discontinue my plan and ask for a refund.
