Hobby charger showing capacity of batts too high?

odd issue here, I’ve got an Ansmann xmove 2 hobby charger which I’ve been testing my laptop liberated 18650’s with but have a rather curious issue in that some of the batteries I’ve tested have discharged a higher capacity than they are rated for?

Any ideas on this weirdness, is the xmove giving inaccurate readings for mAh discharged and if so why does it seem correct when charging?

one such battery in question is a moli icr-18650h giving 2392mAh at a 1a discharge rate despite the datasheet saying it is a 2200mAh battery and the charge before hand ending at 2355mAh

discharge graph

and charge graph which looks correct I believe
