Hi there, Dennis. I'll provide some details to help you clear things up concerning duplicate names in your Products and Services in QuickBooks Online (QBO).

QuickBooks doesn't support the entry of duplicate names for Products and Services to prevent mess and maintain the accuracy of the item or sales tracking. What you're experiencing isn't the usual behavior of the system. I recommend reaching out to our Live Support Team. They have the tools to initiate a screen-sharing session, review your account, and investigate the root cause of the issue. To contact a representative in the correct region, select Global or your appropriate region on this page: QuickBooks Support.

You can also set up reorder points to keep tabs on your inventory. 

If you have any questions or need assistance with your Products and Services, I'm always here to help. Kindly hit the Reply button, and I'll provide prompt support every step of the way.
