Wikimedia Bugzilla is closed!

I wrote a lua template for https://wikitech.wikimedia.org/w/index.php?title=Deployments that almost but not quite works as an initial version. I'm a bit confused though -- it appears that sometimes links are and sometimes not expanded.

I think my syntax everywhere is correct as it all works as standalone pieces.

Could this be because the scribunto version on wikitech appears to be a little bit behind? (It's also missing the mw.text libraries...)

I include a complete code snippet that shows rows with and without expanded links:
