My best guess is that you only copied the Assembly, without also copying the Parts. If this is the case then any changes made to the Parts will affect both Assemblies. In the future I'd recommend using Pack and Go to create the new files, re-naming them as part of the process. See How can I create a new Assembly or Drawing similar to an existing one? if you aren't familiar with the process.
Go to File/Pack & Go then select and change the part names for the items that change, the rest you can keep the same file name if you want.
Use save-as-copy and be sure to include all the sub components with the save. Put them in a different directory - better yet, rename them all w/ some extension, then modify the newly created parts.
