The screenshot shows that your choices are limited. They have no DIK or NEUTRAL affinity. They only have the CHICK affinity.
If you had a NEUTRAL affinity, both options would be open.
Since they had the affinity CHICK at that time, they couldn't change it.
It was because of the way you played. Up to FakeID, you have the option to change your affinity through your play style.
For example, I play affinity-neutral until the FakeID decision and with the FakeID decision I only commit to an AFFINITY (hopefully EP50)
![Stick out tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
for the rest of the game.
With the FakeID decision, DPC removes such options.
You commit to AFFINITY.
As mentioned earlier, as a CHICK, you can still make DIK decisions that cannot be attributed to affinity, and vice versa.
