Resolved in: 2.10.0
Overview of the issue
In WPML 4.3.16 support was added for translating shortcodes that are inside Gutenberg blocks. There is a minor fault where you may find repeated strings in the WPML translation editor when you update the original and change the text of the string in the shortcode.
As you can see on that screenshot, the shortcode attribute string is repeated in the translation editor after it was edited on the original page.
You should translate the repeated ‘updated’ string. This will then be updated correctly on the translated page.
WPML 4.4.0 Beta package
We’ve releassed a beta which should solve this issue. Please, keep in mind that it is a beta version which is under testing and shouldn’t be used in production sites. You can download it here:
