Background of the issue:
I am trying to resolve two separate issues with WPML on my WordPress site. The first issue involves the 'add to wishlist' text, which initially appears in English but then changes to Dutch. The second issue is with the product tabs from the 'Product Tabs for WooCommerce' plugin by barn2, which should be WPML compatible. These tabs were translated using the translation editor, but the default content is showing instead. This occurred after the translations seemingly disappeared. I am questioning the compatibility of this plugin with WPML. The issue can be seen on this page: hidden link
Symptoms:
The 'add to wishlist' text changes from English to Dutch unexpectedly. The product tabs show default content instead of the translated content, and previously entered translations have disappeared.
Questions:
How is it possible that the 'add to wishlist' text changes from English to Dutch despite being translated in string translations?
Is the 'Product Tabs for WooCommerce' plugin by barn2 not compatible with WPML, given that the tab translations have disappeared and default content is showing?
