There is a difference of approved edits and actual edits in my profile

*Editor Stats* shows

>Mudit Kapil had 503 edit suggestions approved, and 67 edit suggestions rejected

But *Badge progress* shows 452 edit suggestions approved so there is a total difference of 51 approved edits in both the stats. 

Does it mean that 51 edited posts has been deleted from the site?

Why is there a difference in counts in  Editor  Stats and Badge progress?
