That PCB legend is asking for trouble, it doesnt make sense as the tant's minus/ground connection is in the same vicinity, so that's probably gnd. Diodes are prone to this confusion as they can be used in rectification, the anode goes to AC if you want + out or it could be the cathode if you want - out. If used as reverse polarity protection the cathode goes to +, if used to protect a mosfet different again, if used in an audio OP stage or CCS different again. Chuck zeners into the mix for more confusion.
Why not print a diode symbol on the PCB and be done with it, a rectangle with line is too wishy washy, someone unfamiliar with discreets might fit a resistor or radial cap.
