Unable to view Explanation in GAF FPM

Hello,

I'm working on a custom GAF FPM Application and added a FPM_FORM_UIBB_GL2 component. I've created a text in SE61 with General Text as document class and added an Explanation element to one of the steps. I could see the text in the UIBB Preview pane but not in the actual application on Portal or directly through URL.

Are there any steps that I'm missing?

Appreciate any inputs!

Thanks,

Arun
