To check, you have added the malts to the 'Fermentables' and the yeast to the 'Yeast' ingredients profiles?
Assuming this to be the case, open the list of ingredients by type. So for the malts, open up the fermentables ingredient profiles. Now, find your added fermentable (malt). Double click to open up the profile for this ingredient. Under the Amount column, there is a place to enter the amount you have on hand and the price if you track that.
Click 'OK' and it should be saved.
