Minimal complete example (in emacs -q): ================================================================================ Evaluate (setq org-agenda-custom-commands '(("z" "Std Agenda" ((tags "select" ((org-agenda-overriding-header "*select*ed"))) (agenda "" ((org-agenda-span 2))))))) (("z" "Std Agenda" ((tags "select" ...) (agenda "" ...)))) (org-agenda nil "z") and get a custom agenda with the default buffer name "*Org Agenda*" (OK). Create a buffer "test.org" and switch it to `org-mode', insert a timestamp (C-c .). Now follow the timestamp link (C-c C-o), and get an agenda with buffer name "*Org Agenda(a:2021-05-15)" (OK). Now re-do (org-agenda nil "z") which has the same buffer name including the date (BUG). ================================================================================ I do not pretend to understand how the global variable org-agenda-buffer-name is supposed to work (not even mentioning the -sticky- functionality here). What I understand is the following: The org-agenda dispatcher let-binds o-a-buffer-name to the global value. "Simple" agenda commands (like a todo list) called from the dispatcher set this let-bound o-a-buffer-name, so they use the correct default value. "Composite" custom commands called via the dispatcher do not set the let-bound value, so they use the original let-bound value (the global value at the start of org-agenda). `org-follow-timestamp-link' calls the `org-agenda-list' command directly (not via the dispatcher), hence sets the global (not a local let-bound) value of o-a-buffer-name. I have little constructive advice to offer regarding a solution. It seems to me that the global variable o-a-buffer-name is only harmful and I would try to get rid of it, but I guess it is necessary for sticky agendas (not using them).
