Well, I know how to fix it, but I dont have contact with author and not familiar with licenses, so I'm not sure if I can fork this mod.
Basically to fix "unknown" names you need to put /locale/ folder from Krastorio 2 mod to this mod's archive. For me I removed all not localisations except ukrainian and deleted all strings that not have "kr-advanced-chemical-plant" in it.
So it's basically 8 strings:
[entity-name]
kr-advanced-chemical-plant=Покращена хімічна установка
[entity-description]
kr-advanced-chemical-plant=Потужніша хімічна установка.
[technology-name]
kr-advanced-chemical-plant=__ENTITY__kr-advanced-chemical-plant__
[technology-description]
kr-advanced-chemical-plant=Більш потужний хімічний завод.
