After Game statistic showing incorrect value - largest critical strike

I've been looking at a lot of the after game statistics values recently, and found some inconsistencies in the form of values that for all intend should have been a 0

The value that i have noticed to be wrong is "largest critical strike". champions that i have noticed this on is are the AP ones and so should only have a 0 or at least very low number incase the person is running some critical hit chance in his runes

in the link is an album with pictures of the statistics and the players builds this should give an idea as to what stats the different champions had

the pictures are from games that happened on the live server, as i do not have access to the PBE

Hope to see this nuisance fixed in the future
