This thread is resolved. Here is a description of the problem and solution.
Problem:The WPRentals theme has a custom user dashboard for property owners. The links to edit individual properties always lead to the original language post.
Solution: The theme stores the dashboard links in transients. The transient values cannot be translated so the links will always lead to the original language. I got it to work by modifying the wpestate_get_template_link function in wprentals/lib/help_functions.php
