The animal companion race selection list is empty at creation. This happens only with the Survivor archetype selected. My guess is that this has to do with how their Nature Bond (Ex) (At 1st level, a survivor must select an animal companion as her nature bond.) is encoded in the /champions_of_balance/cob_abilities_class.lst

It is definitely related to how the archetype was coded up. The new Nature’s bond ability appears to not use the standard druid companions list.
Commenting out the Survivor's Nature Bond ability and removing that grant from the Archetype definition is a workaround, but the actual solution is likely to recode the Archetype with the current FACT style and replace the original Nature’s Bond with a Survivor's Nature Bond that simply adds a companion in the same way the druid Nature’s Bond - Animal Companion ability did.
