I got some weird behavior on a file, so I recreated a smaller example and can reproduce it. Here it is:
---------- #+options: <:t num:t tasks:nil tags:t * test ** sub 1 ** sub 2 ---------- If I go to the first headline, 'test', and do =C-c C-e 1 h= to export the subtree as html, my filename/default title ends up as 'test nil.' If I export with =C-c C-e h=, I just end up with 'test.' If I remove =tags:t= from the options line, the 'nil' also goes away. Any thoughts on why this is happening? Thanks, John
