For example in this question shows changes I did not make, attributed to my suggested edit. I did not change contents of database examples (Qty columns). Similarly, I did not add "(with how many times it occured)". Same thing happened while editing this answer (revision 2). See this comment.
That is a bit problematic, as it now attributes those changes to me.
Did I do something wrong, is that a bug in stack exchange, or should it work that way?
