I recognize you want to confirm why the bundle under Products and Services doesn't allow the duplicate name item, denniskflee. I'm here to shed some light on this concern.
Please know that this behavior isn't a bug in QuickBooks Online. Bundle doesn't allow the double entry name for items since you can add or group these non-inventory and services you sell together. With that, you need to set up a unique name for each.
