Hi! There are a couple of things you should check with the manufacturer:
1. The PDIG1 2×18 male connector should be mounted on the other side of the PCB.

2. The female connectors should not have that gap between the PCB and the connector. They should be fully supported on the PCB. I think it’s because they are using hand-cut 8-pin strips. Instead, I recommend using 32-pin strips, cut only on one side.

3. One of the pins of the PDIG1 connector should be removed and a wire soldered in its place. The pin in question is as follows:


Apart from that, I’ve had a look at it and the rest seems to be fine.
Best regards!
