If you have a unit with no data and would like to only import ingredients from another unit (without recipes) please follow these steps:
To export ONLY ingredients and not any recipes do the following:
1. Create a dummy recipe in the unit with all the ingredients you want to import into the new unit.
2. Add ALL your ingredients to this recipe (or just those ingredients you want to import)
3. Close this unit and open the unit you want to IMPORT into
4. Go to Recipe Manager in this new blank unit
5. Click the IMPORT button at the bottom of Recipe Manager
6. Choose the unit that has the recipe with all the ingredients
7. Import ONLY that one recipe, and all those ingredients will be imported.
