Good and bad news at the same time. Maybe just run it for a bit and have a look at forscan after it has racked up a few km's.
What is strange is that there are no long term figures. They would represent the adaptive feature of the
pcm. eg, the long terms would usually start registering -10 or there about based on your short terms. The computer would reference this at start up and give the engine 10% less with the expectation that this will bring the system back to stoichiometric.
Maybe as it adapts to a complete or close to complete burn the figures, which aren't too bad will fall into line over the next 100kms?
