stock quantity for variable product no displayed

Your plugin is just what I need to deal with bundled products on my site, especially since it is possible to bundle with a variable product. HOWEVER, when the plugin is enabled, the stock quantity of any variable product (where stock quantity is being managed) does not display. This is not a variable product related to a bundled product, just a variable product where stock is being managed. As soon as I disable the plugin, stock quantity is shown as expected.

here is an example of bundled product – but that is not where I am having a problem

the problem is with product where inventory is managed, stock quantity is not displayed. See
https://lindascraftique.com/wp/product/zambesi/
or https://lindascraftique.com/wp/product/handmaiden-casbah-plush/
You can not add more than the available quantity to the cart, but the quantity is not displayed above the add to cart form as expected.

Your assistance appreciated!
