[1.4.3528] (All DLCs) Faction details shows incorrect Xenotypes in Ideology tab.

I've tested this in more saves.
If you have a custom xenotype, in the ideology tab get the "faction details" and it will only show "Faction xenotypes: 100% Baseliner)
Which is not true, since all of my colonists have the same custom xenotype.
See the attached screenshot for the issue.

i've forgotten to say: I don't use any mods, pure vanilla, with a clean game install.
