As I understand the power system is 208/120 3phase. However, the panel in question has only the three phase conductors run to it and does not have a neutral. The loads are all single phase 208 - wired phase to phase.
Since the panel does not have a neutral, how is it (the panel) measuring 120V and a power factor? The numbers don't appear to mean anything.

The monitor is showing you the power factor associated with the current in each of the phase wires. That current and its power factor will be independent of whether the source of that current is a delta or a wye and also independent of whether the loads are wired delta or wye.
However, you have to do some not necessarily simple math to figure out from that information just what the power factors of the actual line-to-line loads are.
In particular, you need to know whether the line currents are leading or lagging, and then do some vector math.
In the case of an unbalanced load, even with a uniform power factor across all phases, I can see the power factor calculated for the
line currents to be different for different lines.
Now if the source did not have a neutral conductor to connect the monitor too, it would not be able to give you the readings it is.
Possibly there is a configuration setting on the instrument for showing delta or wye readings and you can just change that?
If there is no neutral at all, then that could cause the error indication you see.
