Yes it is two GPUs working together to make a R8. As long as both are shown as enabled you shouldn't have any problems regardless of what they get called in the device manager.
If you remove the CD drivers using DDU, then install the latest Crimson 16.7.3 and check the name, it may correct itself.
If that does not work, try downloading the Asus AMD drivers hosted on their website here > X555DG | Notebooks | ASUS Global
DDU the existing drivers, install the Asus AMD drivers and check the name.
