Cannot retrieve all tweets with user_timeline api

any ideas where did other SIX tweets go? the number is under the limits (3200)
is there a bug inside the api?

can anyone here help with? any team member?

They may have been deleted. Deleted tweets still count in the count parameter but not in the response

thanks @richardhyland. I have tried with deletion, the count was also updated accordingly when I deleted a tweet.
