Scenario 1.
I have a catalogue, and a category added to the catalogue.
I add a product and assign a category to the product. The products in the category increases. The products in the catalogue stays the same.
I delete the product. The category count goes down, and catalogue product count stays the same.
Scenario 2.
I add a product and dont assign a category.
I go to the catalogue and add the prodcut to the catalogue. The number of items in the Catalogue count increases.
I go to the product display and delete the product, the catalogue count still displays the same number of products. Actually also noted that the catalogue appears to have an orphan product in there as well, which does disappear. Count though remains incorrect.
The display of the catalogue now appears to show several items which I added and deleted with no images.
