All of my imports work correctly. However sometimes my variants get deleted. If I do an Inventory Import with only a portion of my products variants, sometimes it will delete the variants not included in the import at all. There are no errors or empty spaces. It does not happen every single time all variants arnt on the list. I know for certain its in the correct .csv format. Any ideas?
You need to have all your variants in the csv file even if you are not updating them otherwise the ones you leave out will be removed.
