Attack Information - Immunities

On any pokemon page, when you look to expand the information under an attack, it lists NVE and SE types. However, when there is an immunity, these are wrong, I believe. For instance, Poison Jab is listed as dealing 0.714x to steel, but isnt steel immune to poison? So this should be 0.51x. Dragon Tail is listed as 0.714x to Fairy, but isn't that also immune (0.51x)? Is there something I am missing?

Edit: I have added a screenshot for what I meant with "Counter" (note ghost). Images for Dragon Tail and Poison Jab are below.
