Niel,
This is a cosmetic issue with duplicating resources/items in FieldPoint Explorer. It does not negatively effect the functionality in any way. FieldPoint R&D is aware of it and will address it in a future release.
As a side note, there is an additional step you must take to download the configuration into the network modules when you duplicate a configuration. For each bank (other than the first which was already configured), you must right-click on each I/O module and choose Edit This Device, then you should click on Channel Configuration, at this point a dialog box should appear letting you know that the current configuration of the module and the file (IAK) configuration are not the same. Choose the File configuration in order to download the in
formation into the network module.
Regards,
