On a planet screen, when you adjust your production ratios, the boxes for production, research, & wealth immediately reflect your changes. What does not update is the production time in the building queue in the lower-right corner. The only way to see the queue reflect the changes is to exit the planet screen and re-open it.
Please have the building queue immediately reflect production changes without having to exit, and re-open, the planet screen. The devs should never have allowed this condition to exist.
