*** NEED MORE INFO *** I would like to report some errors for future corrections.

I would like to report 2 bugs:

1- Badge ( when adding latter spacing, and save wysiwyg, it resets to the default value, not saving the value set to be the default.)

2 - Heading ( When adding shadow, it seems to me that the shadow is over the color when trying to match the gradient text.)

Can you please share a DEMO project so I can see all your settings?

The letter spacing issues will be addressed in the next update.

The behavior of the heading cannot be changed, because this is standard browser behavior and it related to how background clipping works.
The gradient "disappears" because the text-shadow is on a level above the background.
Level 1 - The background.
Level 2 - The shadow
Level 3 - The text (which is transparent, because of background clipping is enabled)
