Unfortunately I can't make out the list of flypages on your screenshot, the detail is not clear. I would be surprised if it is not included in the list though.
However to show the module on the product flypage you include the page 'shop.product_details' on the setting for the VM Page parameter. That is the product flypage. Use control-click to add this as well as 'shop.browse'
You only need to select a flypage if you only want to show the module
for one specific type of flypage, normally you do not need this.
This is explained in the documentation:
