You use org-roam-node-insert? Can you copy-paste a result here?

Oh, do your nodes have a #+TITLE line? If there's no #+TITLE, it defaults to using the filename.

Inserting stuff from normal mode ends up before the cursor, which is not what I want if I just typed text ending with a space character, I want it after. I've been using this for a bunch of insert functions:

(defmacro my/insert-after-space (&rest fs)
  `(progn
     ,@(mapcar
        (lambda (f)
          ;; If in evil normal mode and cursor is on a whitespace
          ;; character, then go into append mode first before inserting
          ;; the link. This is to put the link after the space rather
          ;; than before.
          `(defadvice ,f (around append-if-in-evil-normal-mode activate compile)
             (let ((is-in-evil-normal-mode (and (bound-and-true-p evil-mode)
                                                (not (bound-and-true-p
                                                      evil-insert-state-minor-mode))
                                                (looking-at "[[:blank:]]"))))
               (if (not is-in-evil-normal-mode)
                   ad-do-it
                 (evil-append 0)
                 ad-do-it
                 (evil-normal-state)))))
        fs)))

(my/insert-after-space org-roam-node-insert
                       emojify-insert-emoji
                       org-web-tools-insert-link-for-url)

If I understood correctly, the problem turned out to be caused by evil but the post doesn't mention evil anywhere! Always mention evil, and, more generally, explain how to reproduce the problem.
