Let me elaborate.

Your patch adds for columns

         ;; also process actions
         (raw-actions (org-element-property :BEAMER_ACT headline))
         (actions (if raw-actions
                      (org-beamer--normalize-argument raw-actions 'action)
                    ""))

but the existing code also have

          (let ((action (org-element-property :BEAMER_ACT headline)))

at least :BEAMER_ACT is acquired redundantly.

Further, the old code has

             ((and (string-prefix-p "[" action)
                   (string-suffix-p "]" action))
              (list
               (cons "A" (org-beamer--normalize-argument action 'defaction))
               (cons "a" "")
               (cons "R" action)))
             (t
              (list (cons "a" (org-beamer--normalize-argument action 'action))

So, depending on the :BEAMER_ACT value (if it is enclosed into [xxx]),
it is parsed differently.

---

I do not know if [xxx] vs xxx makes any difference for columns, but it
is generally not very clear why there is a distinction in one case but
not another. If using (org-beamer--normalize-argument raw-actions
'action) unconditionally (rather than 'defaction or 'action) is ok, at
least it deserves a comment in the code.
