I think the Pi4 does not have a PD chip so negotiation does not happen. Also, I think there was something about Pi4 having one resistor shared on CC1/CC2 instead of one per line and this made it incompatible with USB-C PD chargers. Boggo standard PSU for Pi4 is probably only/best way to go. Was it ever fixed?
LattePanda Alpha - this seems to have issues with USB-C PD with the PD chip on the Alpha getting confused between being in sink/source modes. No idea if this is related or not but raises a red flag in general. Probably best to use the power brick provided with the Alpha.
