Steps to reproduce the issue

1. Create a category and save in any language [example: en-GB].
2. Click on the Associations button.
3. You will see that the category has been saved, instead of seeing a window with creating a category in another language.

Expected result

On the right you will see a window for creating a category in another language

Actual result

System information (as much as possible)

Joomla 3.9.15, Web Links 3.7.0, PHP 7.3.9, MySQL 5.5.5-10.3.13-MariaDB-log
