Add quantity box appears on some items for no reason

[boinkit]

I have just set up my store and all appears to be working fine, except that some items (and particularly new items) that are in the store had the 'Add quantity box' next to them, whilst others have the click 'more info' button next to them.
Is there any way to change them all to the 'click more info' button?
Or can someone tell me what is different with the new products to make them have the 'add quantity' box next to them. It just looks very odd and I don't know why it is happening.

I fixed this :-)
