Somehow, the Drupal Commerce page at admin/commerce/products/add is failing to recognise that I have product types and is giving this misleading error:

> You have not created any product types yet. Go to the product type creation page to add a new product type.

From [reading this discussion](https://www.drupal.org/node/997444) and [a look at the code here](http://cgit.drupalcode.org/commerce/tree/modules/product/includes/commerce_product_ui.products.inc?id=78a038688464752ab499adda1a8a58f5195ef1bb) it looks like the Commerce module on this page bizarrely gets the list of product types from looking at the menus. There's a heap of "what worked for me was moving X to Y in the menus" but they all seem to be slightly different and match older menu naming conventions. [This issue](https://www.drupal.org/node/932194) appears related but isn't. I have editted the Commerce menu and would like to keep my editted menu how it is.

How can I make sure that Commerce recognised my product types on this page? What has to be where for this page to recognise product types (or even better, is there a way to make it happen the normal way via entities instead of via menus?)

I've also tried bypassing my broken admin/commerce/products/add page completely with a redirect, but the redirect is ignored.

I've also tried moving my Products > Create Item auto-generated menu links back under Store in the Management menu, and creating new menu links to those pages under Store in the Management menu, but neither works.
