The symbol is upside down to convention (the gate usually comes out from the source side), but as the substrate is connected correctly, and the default model isn't asymmetrical (D and S are interchangeable), it doesn't actually matter.
Also, this is the first time I've seen those outrageously wrong MOSFET symbols in a slightly-less-wrong configuration:
Luckily you put together the circuit correctly, despite that.
If people would realize that the original, and actually correct and useful, MOSFET symbol actually
means something, by itself, this wouldn't be confusing.
