Simulated Button doesn't seem to work

I have want to add my computer to my network via Wake On LAN, I want to be able to remotely connect to it and this requires being able to power it on remotely. Wake On LAN works, but due to some issues of seemingly someone spamming wake on LAN packets to my home network when port forwarded for WOL, I want to do this through Smartthings.

Anyways, I have drafted up an app and it seems to work in testing, my only issue is that I use a Simulated Button, and the button does not appear in the app, I cannot press it in any way. Is this a bug?

Did you create the DTH for the button or pick it from the generic drop down menu? I have many simulated buttons and they are working fine.
