Tasks cannot be completed in the Contacts view

I have an automated task set up when certain tags are applied.
Previously - I could click on the contact and then look at the task - and mark it complete.
Now when I click on the task it shows me a drop-down for who the task is applied to - but there is no task.
When I go back to the task view list - I can see it and mark it as complete.
Is this just me - or is this a poor way of managing tasks in contact profiles?
