Thank you. Unfortunately, I know embarrassingly little about how to read a schematic. But this will help fix several issues I'm sure.If you check the schematics...
You can see that Pin 2 of UE13, goes to the positive side of C12, and to the resistors R44 and R43, that most likely are in the backside of the PCB and are connected to the pad you marked as "B", so, maybe this can help you to interpret the connections, but in general, if you see a trace that goes to a pin then you should always get connectivity between all ends of that trace, and if you don't, something needs to be fixed.
