Deleted variations still showing in list

Hi,

Hoping someone can advise with an issue…

I have a horseshoe product which has the Attributes: Orientation (Front, Back), Style (Clipped, Unclipped) and Size (1,2,3,4,5,6,7,8,9,10).

If I create variations from all of these but delete sizes 1,2,3 for “Front”, “Clipped” then select this combination from the product page I still see all of the sizes listed.

Is there a limitation as to the number of attributes which can be utilised in terms of the conditional logic, or have I missed something here?

Thanks
