I had quitted this game after the egyptian hospital abuse and I hadn't downloaded the update. But I keep contact in whatsapp with some club members as we've been together for years and this morning they said the COM was not working, so I finally downloaded it and I've checked this has also happened to me: I've dispatched lots of trains but the daily task, the same as yours, keeps 0/5.
I had also the weekly task of transporting 1000 travellers by train. I've completed it, so the table should show one of the five remaining tasks, to have access to ten daily tasks again.... No. It has remained with only nine tasks.
It's a completely disaster. EA has gone too far. And they have added not one more sort of coin, but three: popsicles, ice coins, and now golden tickets are currency too.
They're doing it harder and harder. It's IMPOSSIBLE to enjoy this game. It's pure rubbish. It's a time sucker that destroys lifes with no benefit at all.
I'm more convinced than never that I won't get back into it.
I've edited the post with images where you can see I have only nine weekly tasks where it says there are still five more to appear, and I have the train daily task to zero, although sending passagers was precisely the weekly task I've completed.
