Exclude from category

I purchased this plugin yesterday and am struggling to get it to work properly – The exclude category seems to ignore some of the categories – I have one excluded called ‘headgear’ but the item with headgear as category has the add to cart button removed and there is not even the ‘info’ button – on some others there are no buttons at all!

It does not make sense which items have which buttons – some items have the info button at the top of the page as well!

I am using the latest version of wordpress
