Confirm this electrical hook-up is wrong

Last week I was doing some work up in my battery compartment and noticed what I think is a hook up mistake in the battery wiring. Before I change this, could someone just confirm that the line side of the 80 amp breaker should be hooked up to the line side of the 50 amp breaker. Currently it is hooked up to the load side. To me itís obvious, but the fact that I have never had the hydraulic pump trip the 50 amp breaker introduces just enough doubt in my mind that maybe I am not seeing this right.
The yellow arrow is the line from the battery, the blue is the line to the 80 amp breaker and the red is the 4 ga to and from the converter/charger.
Thanks.

Yes, it is incorrect.
As it is, the 50A breaker is in front of the hydraulic system 80A breaker.
Move the blue arrow wire to the same terminal as the yellow arrow wire.

The red cable connecting the two 50A breakers looks a little small. It should be 4 gauge.

I installed bus bars and a battery disconnect.

Thanks for the confirmation. I was pretty sure of it but I usually question myself when I see something oem and think I know better. Thanks.
Also, you are correct, the jumper wire to the other breaker is not 4awg, it is 10 I believe, but that breaker is 30 amp, not 50.
