Missing Typography Button - Custom HTML Module

Trying to use Typography in a Custom HTML module, but the button isnt at the bottom of the editor. I modified some of the options of the module, which stripped out the GK Typography in use there.

Any help appreciated

Hi,
first , if you modified some of the options of the module, which stripped out the GK Typography in use there, I'm not a Wizard to tell you what have you done and how to fix it.
Second, but I can tell that you can still use typography using code, you don't have to use button for dummies.

I understand the use of the typography codes...Im just trying to work out why, when all I did was change the name of the module for "about" to something relevant to my site, it no longer recognised the gk typography code in the custom html area.

Even I wipe all the code and start from scratch, it doesnt recognise it.

The GK Typography plugin is enabled and set to full.xml but it doesnt allow me to use it (and the button is missing from the module, and I cant use it in K2 article editing either)
