In the documentation, it states the following for syncing URLs of pages:
- Change page URL path slug - the URL slug of the page (and path of its child pages) was changed.
- Generate page URL paths - URL paths of pages were generated, as a result of, e.g. changed routing mode.
- Update page URL paths - URL paths of pages were updated, as a result of, e.g. changed URL format.
- Delete page URL paths- URL paths of pages were deleted, as a result of, e.g. changed routing mode.
Since none of those actions were actually performed during the "full sync", those paths are not updated/synced to the other environment. You'd have to manually trigger those by saving the page URL or creating some code to go through and create the tasks by doing "save action" in code.
