Multiple Packages “Group by Shipping Class” hides shipping methods

The topic I created weeks ago has received no response. Please advise:

The Multiple Packages for Woocommerce plugin causes the shipping total for products that doesn’t have Free Shipping to say “No shipping Options Were Found”. When the plugin is activated, even though it is disabled in the Multiple Packages settings screen, it still interferes with the package options in the Cart, even when there is only one product in the Cart, which would otherwise display shipping options. However, when set to “Group by Product”, or when the plugin is disabled, the Cart works properly, without interfering with the display of the shipping methods. FYI, currently on the site, “M-Audio BX5 Monitors” is the only product without free shipping. To recreate the issue, add that product to the cart, whether or not another product is added.
