Problem with Qsys when creating PIO

[Altera_Forum]

I am beginning to create a hardware with Qsys. 

The system that I want to create has 4 ports: clk(input), reset(input), a1(input), a2(output). I added a nios processor, a on-chip memory, a jtag uart, a pio_0, a pio_1. I also followed step by step as the instruction of creating the simplest nios program said. I set pio_0 to be input, pio_1 to be output in Basic Settings/Direction. However, when I generate this hardware, it only has 2 ports: clk and reset. I saw that 2 PIO components have external_connect but I don't know where to connect them.  Would you please tell me why I can't create 4 ports?

Double click the 'external connection' and you should get a name you can edit. Put a suitable name here, then generate, and you will have the relevant signals as ports on the QSYS system.
