Ritual #4 issue

Hello,

I've recently had issue with rituals where the fourth one is not available to start but was okay at the beginning of the map. I don't know if it occurs after completing the third one or if because the map is been completed. On the picture you can see that three are completed but fourth is unavailable and marked as not done on the map. (Sorry I can't put the print screens I've done, let me know if you need them and how to proceed)

The atlas node Spreading Darkness is selected.

Regards.

****Update****

I've done the fourth ritual before completing the map so it would mean that it blocks the ritual if the map is completed.
