Fatal Errors with Custom Post Type v2.6.2 update

I have a WooCommerce store and use the full suite of MetaBox plugins. I recently upgraded to MB Custom Post Type v2.6.2 and found that a series of fatal errors occur in the store that appear to go away when deactivating the plugin or downgrading back to v2.6.1.

A number of the new issues that appear when v2.6.2 is active are:

1. The name / sku / stock etc. content on the WooCommerce Products admin page is blank
2. Trying to edit a product causes a number of PHP fatal errors such as: "Fatal error: Uncaught Error: Call to member function get_catalog_visibility() on bool..."
3. WooCommerce Products do not display on product pages
4. A PHP Error is thrown for register_post_type() by the mb-custom-post-type component: "Function register_post_type was called incorrectly. Post type names must be between 1 and 20 characters in length. (This message was added in version 4.2.0.)"
5. A PHP Error is thrown for register_taxonomy() by the mb-custom-post-type component: "Function register_taxonomy was called incorrectly. Taxonomy names must be between 1 and 32 characters in length. (This message was added in version 4.2.0.)"
6. A PHP wc_doing_it_wrong error shows numerous times per page "Function wc_get_product was called incorrectly. wc_get_product should not be called before the woocommerce_init"

These issues appear to be resolved by downgrading to v2.6.1.

Has any one else seen issues with v2.6.2 and have you resolved them? Hoping there is a resolution out there.

Many thanks!
