Cannot Add Pets anymore because of Alchemy

[LUC1G07CH1]

After installing the alchemy mod,i just cannot add pets anymore. I also cannot add items that can be created with alchemy.

Does anything have to be fixed or i need to uninstall alchemy? Because i want to add new pets/items again,there is suposed to have millions of pets.
