Wiki TOC doesn't show page titles (BB-6592)

Trying to use the Wiki TOC as per this guidance:

https://confluence.atlassian.com/display/BITBUCKET/Adding+a+Table+of+Contents+to+a+Wiki\\
https://bitbucket.org/marijnvanderzee/build-wiki/wiki/TocTests

But, when i sue

#!macro
<<toc / 3>>

I am not seeing the current page's title or the title of sub-pages.

Can someone checkout why the macro is not showing these?
