call to action is just saying that if you press that button, it will take you to a screen where you can do the objective. So when the objective is done but it hasn't updated, it is displaying that instead as usually it would show you the specific call to action, e.g. start a raid or whatever

Edit:
It's spreading, up to 4 now. And when you complete a "call for" task you do NOT get credit for it.
The 4 I was speaking of just "caught up" and gave me credit for completion, so it only shows what is in my photo again.
Looks like a refresh problem: closing and reopening the game will let you get the reward
