Sidebar not showing up in posts

Hi!

I added a plug-in, custom sidebars, that allows one to customize sidebars and add them to posts, pages etc…

PROBLEM: It only shows up on certain posts and not on others. One one posts I decided to delete the old posts and cut and paste the text into a new post and that fixed the sidebar problem.

Am I going to have to do this on every posts that the sidebar is not showing up on or is there a bit of code( I am NOT experienced in writing code YET) that I can add to the text editor of that post to make the sidebar show up. Here are two examples:
