Tabs or blank at the beginning

Hi,

installed a few minutes ago sublime does not highlight/preview markdown text properly. This here works:

Package Control Messages
========================
Markdown Preview
----------------
Sublime Text 2/3 Markdown Preview
=================================
Preview and build your markdown files quickly in your web browser from sublime text 2/3. 

These lines here not:

Package Control Messages
========================
Markdown Preview
----------------
  Sublime Text 2/3 Markdown Preview
  =================================
  Preview and build your markdown files quickly in your web browser from sublime text 2/3. 

Tab/blank no matter where you place it seems to break the following markdown lines. Using Sublime 2 on Ubuntu 14.04.4 and Monokai-Extended, Markdown-Extended, and Markdown-Preview.

Best regards Mladen
