Why is my software not producing the correct Avalon write?

I have my nios connected to an Avalon memory mapped bridge that will allow me to communicate with an external RTL component. All I am trying to do is read and write to a register in the RTL component...

Be careful with Avalon bridges. Check that you address is in DWords and not in symbols. Your address 0x20000 might be actually translated to 0x8000.

I did make sure to set the address to words.
