I don't think the footer is working as expected

[Metal-Milonga]

The %footer does not seem to behave like %title or %date in the individual zettels. When I create a new zettel from an existing one, the footer is not carried over to the new zettel at all. I don't know much about Vimscript, but looking at the vimwiki.vim that came with vim-zettel, there does not appear to be anything obviously wrong.

These are my only Vimwiki/Vim-Zettel settings in .vimrc.

" define a vimwiki in ~/Dropbox/zettlekasten directory.
let zettelkasten = {}
let zettelkasten.path = '~/Dropbox/zettelkasten/'
let zettelkasten.path_heml = '~/Dropbox/zettelkasten_html/'
" now put the Wikis together in the vimwiki_list
let g:vimwiki_list = [{}, scratch, zettelkasten]
let g:vimwiki_folding = 'expr'

" ZettelKasten settings
noremap <leader>zn :ZettelNew
