Strings not highlighted anymore

[lra]

I use a theme that's supposed to highlight strings (in green): https://github.com/atom/atom/tree/master/packages/one-dark-syntax

Up to today, it was highlighting strings in terraform too. But not sure what changed today, strings in terraform are not highlighted anymore:

Any idea how to highlight strings back?

Other languages are fine, e.g. python:

It seems specific to this package, and recent.
