I think I spoke too soon as I've tested the code again on another document I'm working on and its now making all the manual sub level numbering bold. I will go have to go back to my original code and figure out how to update the IF Statement to include to move one space if paragraph starts with an opening square bracket. Completely my bad as I didn't originally include any sub levels within the test document or images so my apologies for that.
