I have noticed that in all IR machinery that has configurable sides using the screwdriver they sometimes reset to their default side selection once you exit the Config UI OR they have mismatched off-synch selection modes between the UI and what you see on the blocks and the issue is especially persistent in the Lazuli energy storage blocks to the point that i had to change my setup around the block instead of trying to config the sides.
At first I thought that it was a latency thing in the server because bad TPS usually affects block updates just like everything else (playing in aof5 EU server) but when I tested it in my SP world it did the exactly the same thing..
and no it's not a visual bug cause I tested with power cables, they were not able to transfer power until the blocks showed the right output/input mode in the world and not the UI!!

Check images below to see the bug in action, UI and the block behind it don't visually match.
When I change mode in the UI the block displays the previous mode i had so it's always a mode off-sych
but in rare cases it follows it correctly.
Exiting and re-entering the UI doesn't fix/re-synchronize it either. But it some times resets it to it's default randomized pattern.
