halui.mdi-command-NN pins not showing up

Hoping someone can point out the probably obvious error in my configs that is causing halui.mdi-command-NN pins not to be created.  The halui component loads and the rest of halui's normal pins show up in the HAL Configuration tree; in the [HAL] section I have the HALUI = halui line; I've made sure the [HALUI] section in the INI file exists and that there are MDI_COMMAND entries under that heading, but still no joy.  Can someone see what I've missed? 



Thanks.
