see uploaded screenshots of attributes, attribute size
I've also uploaded a screen of WPML Settings for user defined meta, which I used to set "color" to "copy" - that worked for my color attribute swatches.
still don't know what to do to make my size attribute showing up as swatches, too
2. Make a small change to the product title/content > Save changes > Update the translation.
3. If it does not work, please go to WooCommerce > WooCommerce Multilingual & Multicurrency > Settings > Troubleshooting > Enable "Sync products variations" > Click "Start".
I would like to request temporary access (wp-admin and FTP) to your site to take a better look at the issue. It would be better to a testing site where the issue is replicated. Your next reply is set to private to share the info.
❌ IMPORTANT: Please backup your database and website before proceeding ❌
You can use this plugin to create the backup: https://wordpress.org/plugins/duplicator/
✙ I would need your permission to de-activate and re-activate Plugins and the Theme and to change configurations on the site if needed. This is also a reason the backup is critical.
When I edit a size, for example XS, I do not see a color in the option Color Swatch is set. Then I set a color (purple) > Save and the size attribute in the frontend display as swatch correctly, please check this screenshot hidden link
For other sizes, please go to Products > Attributes > Größe > Edit a size > Set color in the option Color Swatch.
