Treaty weirdness - bug or feature?

[PvK]

Ok, saw something new and bizarre just now. Anyone seen this or know what's going on?

I look at the treaty grid, and see empire A has partnerships with empire B and empire X. I am peeved, because empires A and B just broke their treaties with X at my request. So, I send a message to A telling them they are bozos and breaking treaty with them. So far, no bug.

Then I go look at the treaty grid. It no longer shows ANY of the treaties mentioned above, as if the reason for my breaking treaty was false. I know I wasn't making up seeing it that way. So, either this is some sort of treaty display bug, or it's a feature I don't understand. Is it required to have a treaty with an empire in order to see its treaty statuses with other empires???
