Hi, same issue for me like if translation and display conditions were in conflict.
Hi I solved.
I am not sure what of the 2 things fixed it.
I first upgrade a plugin, and second I made a backup with duplicator, deleted the website and restored it.
That issue appeared on the last 2 templates, but the previous ones, with similar conditions, were still good, so I thought it might had to do with for example permissions or anything not easy to identify.
If all your plugins are already updated (take care also of those that do not receive updates automatically: in my case the plugin had to be updated manually), try duplicator.
good luck
Hi. Update: I thought I solved but in fact I did not!
I’ve just modified a template in a language and the other language lost the template.
I tried to deactivate the plugin I mentioned, but it did not work.
I noticed that the “new theme builder” does not work with languages. If I try to set a conditions with it, I only get categories in the default language and I am not able to set other languages.
I also tried to unlink the languages between templates, but it did not work.
I am stuck now…
This is basically the same issue of this topic: https://wordpress.org/support/topic/display-conditions-reset-when-editing-a-template/
But it looks like the issue is not of much interest.
I found a workaround.
There must be something to fix between with the new Theme builder of elementor and polylang.
