[2022] Green books for nurseries are missing

Hello Guys,

I am trying to boost my nurseries in the new world with some of the books like Hand-pollination Method, Double Redundancy or Interspecies Grafting. But i cannot finde them in the research institute nor at Archibald.
I can find the orange, yellow and a few white books, but not a single green one.

I do not have a stage 3 investors skyscraper yet, only a bunch of 2 stage ones.
I do have every DLC except the anarchist and botanica.
Do i have to unlock these items somehow?

Thx in advance guys. If you need additional information please let me know.

Regards.
