 I am having trouble altering custom code for different pages if I type {% section 'image-bar' %} under my services page and I type the same line of code under my page. The sections show up exactly the same on each page and I can not edit one without the other changing as well. I have also tried 'image-bar2' same thing does not work  

Other way of explaining.. I inserted an image bar on my page and I added an image bar to my and they show up the same on both pages if I edit one it show up the same on the other pages as well I want them to be able to edit independently
