Legendary ilvls incorrect?

When using upgrade finder, BiB, and BiS, Ask Mr Robot is telling me to use ilvl 970 legendaries, but I have my filters set to use ilvl 940 legendaries. However, when I set it to ilvl 970 legendaries, its making a couple of them (most commonly, but not limited to, legendary rings) ilvl 1000, which as far as I know, does not exist at all. Is there a way to correct this or is it just a bug?

Looks like two item level bonuses are getting applied… Blizzard got a little wacky with the IDs on the legendaries and used several different ones. I’ll change it in the next update.
