Can't see when truce ends

[Yepe]

I can't see when my truce ends if I dissolve an alliance. It's a semi minor bug but also very annoying because 95% of the time the reason why I dissolve an alliance, is because I plan to attack.
100% repro, happens also to friend:

1. Be allied
2. Dissolve alliance
3. Open diplomacy
4. Observe that the truce isn't showing in the list
5. Click declare war
6. Observe that you would be breaking truce, so there is a truce.
