Changing phase from A to something else then back to A

I have tested choosing the wrong phase designation. When it was on A the watts were 127, and pf:0.95
Anything else brought it down to 98 Watts, pf: 0.74
I put it back to A expecting it to go back to the higher values, but it did not. Am I missing something ?

It looks like the load changed. But more importantly, it’s possible that the CTs are not all oriented the same way.
