I wrote to the support of the theme, as one problem persits, when I am coming from a portugues property and switch back to english, the slug dont changes, just the domain name. But when you press Clear WpResidence Cache, it goes to normal.
I translated now a property without disorder in images, only issue is that the second language shows the featured image as the first image of the slider (gallery) what in english not is.
Thanks for your reply. I couldn't find any issues with the current image display settings. To test further, I created a new property in English here: hidden link and translated it into Portuguese: hidden link . The featured image is displaying correctly without any duplicates. Could you try creating a new property on your end and check if it works properly?
