Background of the issue:
I have a Custom Post Type (CPT) named "camps" which uses the native "Categories" taxonomy. I want to translate its URL structure from English to Polish, while keeping the category slug in the URL. My goal is to achieve the following structure: EN version: /camps/category-name/post-name/ PL version: /obozy/translated-category-name/post-name/. To do this, I go to "WPML" -> "Settings" -> "Post Types Translation". For the "camps" CPT, the original slug is set to "camps/%category%".
Symptoms:
When I try to enter the value "obozy/%category%" in the translation field for the Polish language, the input field does not allow me to type or save the percent signs (%).
Questions:
Is the method I am trying to use (combining the translated CPT slug with the %category% placeholder) the correct and supported way to do this in WPML?
What could be causing the input field to block the "%" characters? Is this a known issue or conflict?
