Event Bug Task not updating

[soft barn]

So I got that task to create 5 of these white Ointments even though my laboratory was still on lvl 3.
Took me 2 days to upgrade laboratory and luckily had just enough material to create 5 of them but task doesn’t update.
Please help

Turns out the German translation is wrong and it actually means the yellow one.
Great, wasted 2 days and many uncompleted tasks because of that
