Steps to reproduce:

  1. Accept the day's Daily Tasks.
  2. Unfocus the displayed task focus: "Do Not Display Task Information"
  3. Cross zone lines, or break a green chest.
  4. Task gets focused again.

According to

A bug has been fixed where task details for tasks that the player had not chosen to focus on were visible in the task window.

Looks like you have more than one "bug" causing this. It also looks like you never tested your bugfixes...
