My issue is I can not seem to map the second EX2 on my network.
I can not see it to add.
There is a specific subforum for discussons on the EX Series of My Cloud devices that are running the OS5/v5.x firmware.

If one has two or more My Cloud devices on their local network they will need to ensure each My Cloud has a unique name. This means accessing the My Cloud Dashboard > Settings > General section, and setting a unique Device Name then select the Save button to save the changes.
