Tell us what you are trying to do? I just noticed that the last 11 product attributes and all their terms we added and configured on our products are gone from the WooCommerce Attributes / Single product page. Looking in the database, the taxonomies are still here, but the last one we added are not displayed in the backend.
Is there any documentation that you are following? No
Is there a similar example that we can see? No
What is the link to your site? hidden link

I'm really not sure what's going on but the only thing we did related to taxonomy modifications is the addition of Toolset on our website.
We have 16 product attributes configured: Colors, Size, Brand, Manufacturer, Collection, Composition, Content, Made-in, Closure, Profile, Crown-size, Brim-type, Age-range, Panels, Model and Structure.
The first one were added since a long time ago: Colors, Size, Brand, Manufacturer, Collection
These 5 product attributes are visible in the back-end but all the other ones are GONE! They also don't show up in the single-product backend page. We have spent hours configuring these 16 attributes across our hundreds of products.
I have verified and the taxonomies are still here in the WooCommerce table "wp_woocommerce_attribute_taxonomies" but it seems like something is broken somehow.
I tried to use WooCommerce tools to rebuild the database but the product attributes are still not showing up.
Please tell there's a way to fix this!
Waiting for your feedback.
Thank you!
