Hello Docktorkain! 

The tooltips of Infrastructures and Districts stops to appear after making it appear once and then opening any other Civic.

For example:

1. Open Artistic Ownership Civic.
2. Check the tooltip on the Artist's Studio infrastucture.
3. Open any other Civic.
4. Go back in Artistic Ownership and check the Infrastructures' tooltips.

Unfortunatly there are no workaround once the tooltip has disappear except relaunching the game, trully sorry for the inconvenience.

Thank you for taking the time to send us your bug report, we'll investigate a solution!

I was suggested a workaround by sic_kapkan which I'll include in the my mod (Vanilla Improvement Project): I'll create a dummy effect for those civics with a text explaining the effect of the unlock. its a way  to "fix" it without requiring any codechange (well, it'll need some translation work, but that may easier/cheaper than bugfixing)

I coded in a workaround in my mod by creating a dummy effect and using a custom tooltip. Its not the most beautiful solution but it works:
