Wrong canonical url

Hi, When somebody shares a url from a user page https://alivetoearth.org/user/tom the link works, but Facebook doesn’t recognize it and gives a 404 error as you can see here: https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Falivetoearth.org%2Fuser%2Ftom . I found out what is the reason, the canonical url is https://alivetoearth.org/usertom while it should be: https://www.alivetoearth.org/user/tom . This page is generated using crocoblock’s JetEngine plugin and I use rankmath, do you have any idea how to solve this issue?
