I noticed last patch that there seems to be bug where pet damage stops showing the numbers even when you have "Show Damage" and "Show Critical Damage" turn on. I believe it might be intertwined with the damage calculation itself somehow as it seems to bug out when I start trying to remove/put back on Feast of Cankers. Once the bug begins, I cannot get rid of it without logging out.

The whole problem began because I was trying to test out to see how much increased damage the nodes and Feast of Cankers cause my summons to have. I can't even tell if Feast of Cankers are bugged (supposedly they used to be, but I don't know how to test it).
