Heading text color reverts to black after saving in quotes

I am experiencing an issue where the heading text color in quotes reverts to black after saving. When editing, the color appears correctly, but after saving, it changes to black. This behavior occurs on all draft and existing approved quotes, including templates.

Steps to reproduce:

• Go to this quote

• Press edit on top widget (See the header turns orange)

• Press save (see header turn black again)
