Problems styling horizontal QScrollbar

Hi folks!

I am having problems styling horizontal QScrollbar, specifically in the background image of it. The left side of the scrollbar bg, does not appear.

I am attaching .qss file and the images of how it looks.

Any tip?

Thanks in advance.

Cheers.

NOTE/EDIT: look in the left side of the horizontal Scrollbar, you will see no BG image there, which does not happen in the vertical even when i am using the same style of stylesheet code.

EDIT2: never mind, i was making a mistake in the addPage and subPage having this:

QScrollBar::add-page:horizontal, QScrollBar::sub-page:vertical in the horizontal section. The error is used vertical too in the subPage... :P
