I have definitely written and posted 10 stories. None are hidden and you can count all 10 on my profile. Yet my profile info says it's only 8. A bug?
Perhaps you should mail a story moderator about that.
I have a similar problem. I have written 52 stories, yet my profile page lists 45. There were 7 stories which I had hidden, so I restored them to visible and yet the count on my profile page still shorts me by 7 stories. I went to the help desk because I qualified for the Author50 badge and asked why my count was different than the profile count. I inquired because I wanted the count to accurately reflect my work and I felt I should get the badge. Well, I got the badge but my profile count is still 7 stories short of what I have done. No explanation was given.
How long ago did you 'unhide' those 7 stories?. Some updates to various fields on profiles etc. are not done instantaneously rather there are daily or perhaps or even less frequent routines that bring things up-to-date (badges, unless applied manually, are I understand a good example of this).
