They are not supposed to be weaker at all. It's strange that there's no AC printed, however there's a simple pattern we can see if her look at the ACs for every other Eidolon.
Eidolons can only start with either 14 or 18 Dex. The ones that start at 14 Dex have an item bonus of +2, with a Dex cap of +3. The ones that start at 18 Dex have an item bonus of +1, with a Dex cap of +4.
Using that knowledge, we can surmise that the Undead Brute has +2 AC with a cap of +3, and the Undead Stalker has +1 AC with a cap of +4.
Which does make sense, the problem is that where it tells you how to read an eidolon entry it doesn't say something like that and instead just says "Choose from one of two arrays for your eidolon. This choice sets its ability scores, as well as the form of its defenses, as represented by an item bonus to AC and its Dexterity cap."
It looks like someone missed it by mistake and people are just making logical assumptions which would be valid. But the main reason I am bringing this up is because the PF2e Companion Compendia module for Foundry VTT is missing this as well. I brought this up with the creator of that module, but they won't change anything since technically it matches the source material and needs to be clarified by Paizo.
