Keep showing additional tab in some of single products

Previously, I had two tabs on my single product page by WooCommerce. But, when I updated the Accordion plugin to 2.2.10 it shows three tabs on some of my single product screen. The third tab is the post which I had created in the Accordion plugin. When I open that tab in a single product it shows Content missing.

The screens which show an additional tab have an error in the console SyntaxError: unexpected token: identifier.

I tried to find out any solution for this but no luck yet.

Please help me to figure this out asap.
