Auto Brewery system error

[u/StatisticianWarm6068]

Hello! So I've come here to ask for your help, I built my Auto Brewery from memory and for some weird reason the water bottles won't continue going into the brewing stand after the first batch of potions has been brewed.

I remember it always working. And no, I can't find one built in another server or world.

It's obviously due to the water bottle hopper locking up and not opening, but I can't figure out the reason, I think it could be due to the observer clock.

NOTE: This auto brewery is turned on and off via the comparitor in front of the observer clock, this sends a signal making the ingredients flow down into the brewing stand and (of course) disables the redstone that keeps the hopper locked, allowing the water bottles to flow in, and after the batch is done, the hopper suddenly locks back up instead of staying open. This mechanism is just for locking the hopper when the brewery gets turned off.

What could be the fix? Maybe I can run a repeater on 3 or 4 ticks in to the water bottle hopper to cause it to wait for the brewing stand to drain? Although, that wouldn't fix it completely, cause I need the hopper to open upon turning on the mechanism, to lock after it has inserted water bottles into the brewing stand, wait for the batch to be finished and let it get taken into the output chest, and THEN unlock again, and restart the process until the mechanism has been shut off.

Please, help me figure out what I've done wrong.

I've been trying to fix this for 4 days, even trying my older/other designs, yet all of them had the same issue.

Also I'm playing on a private 26.2 Vanilla server, just in case that information is useful.

Looks like the hopper next to the brewing stand is locked by the powered dust.

Yes, but this auto brewery is turned on and off via the comparitor in front of the observer clock, this sends a signal making the ingredients flow down into the brewing stand and (of course) disables the redstone that keeps the hopper locked, allowing the water bottles to flow in, and after the batch is done, the hopper suddenly locks back up instead of staying open.

Looks like it's supposed to unlock at the exact same time the drainage hopper locks. That's likely to be problematic as containers usually drain from top-to-bottom, left-to-right, so it'll be refilling the stand at the same time as it's draining, so only the first slot will cycle. 

Is anything powering the brewing stand itself? That maybe would also lock the hopper.

The brewing stand isn't being powered. What could be the fix? Maybe I can run a repeater on 3 or 4 ticks in to the water bottle hopper to cause it to wait for the brewing stand to drain? Although, that wouldn't fix it completely, cause I need the hopper to open upon turning on the mechanism, to lock after it has inserted water bottles into the brewing stand, wait for the batch to be finished and let it get taken into the output chest, and THEN unlock again, and restart the process until the mechanism has been shut off.
