It doesn't always show a progress bar but the game's still tracking your progress, you seem to have 4 different supply buildings (I can't see clearly all buildings you own) but if you do have 4 different and you collected 8 times from them combined, you still don't meet the requirement as the game would count them as being produced 2x for each buildings so either do another 8 times or 2x 4h from the same building.
Basically as explained above, the quest asks you to produce 4x 4hours production from the same type of building (example = goat farm).
So if we use the goat farm, you either have 4 goat farms and you just set 4 hours production and collect once, once its ready (total wait 4h) or you collect and set production 4 times on the same 1 goat farm (total wait time 4x4h = 16hours).
Whats your ingame name, I'll check your town you probably need to continue producing 4h stuff.
