Sticky Links - When Sticky Links is enabled, the link is shown in its raw state after processing the links.
Solution:
This is expected. When the WPML Sticky Links addon is installed and you have enabled it to make your links sticky, then it is expected to see such a URL pattern. WPML makes it to avoid broken links in your content, although internally you will see these links in this format (?post_type=ID) when clicked they are automatically converted into a permalink structure set up in your WordPress Dashboard > Settings > Permalinks settings.
