Civil Engineer not working at all

[Matrix]

I've seen a bug before about the city screen not being updated when using a civil engineer, but this time it seems the civil engineer is not working at all.

Look at (e.g.?) Seattle in this savegame.

Entertainer:

Tax Collector:

Scientist:

Policeman:

And here's the Civil Engineer:

CEs only work with improvements, and they don't add shields to the production display. When I opened the save, Seattle was building a settler; but if the build was changed to a granary (first improvement build available), the turns-to-complete did reflect the impact of the CE even though the shields don't appear on the production display. In other words, the CE did properly affect production, it just doesn't show up on the display (either a design decision or a previously noted display bug).
