Edge case issue

I know this problem might not be yours, but wanted to ask anyways.

I wanted to limit a bundle subscriptions with your plugin and it shows the worning at the top but still adds a 2nd one to the cart.

We are using https://wisdmlabs.com/assorted-bundles-woocommerce-custom-product-boxes-plugin/ and https://github.com/Prospress/woocommerce-subscribe-all-the-things.

I had to use inspector to show the inventory tab too.

Product type is “custom bundle type”. https://www.dropbox.com/s/8fkfqjkdq37u6h0/Screenshot%202017-02-15%2010.44.12.png?dl=0

Any pointers?
