Dispatch time error

[barrpoxo]

I have a dispatch time of 15days. Just recently After making a sale some of my Dispatch dates are saying dispatch in 2days.

Was this a glitch perhaps?  Which item is affected ? 

The ones you have listed all show a 15 day dispatch time,  as do your recent sold items.

An example of what I mean is item 153952990798 Frank Tyson autograph. Sold yesterday 24th June.
When I go to my sold items, it says dispatch by 25thJune next day. I’ve taken a photograph but cannot display on here.
