This is because you have two filters for product name:
When you create the dashboard action, it creates the action filter for product name (the one in italics), however you've got an additional product name filter. So when product name filter =1, the action filter is still on the item which was selected. As you cannot have two filters working with an 'And' logic, you'll need to remove the product name filter and use the action filters as your filter.
To do this, remove the product name filter, then right click on the action filter and show the filter:
I'd also bring this action filter to be the filter used in your dashboard.
That makes total sense when you explain it like that!
