I can reproduce your problem by creating the same context multiple times. If you set the Sidebar filter to Active Contexts, possibly only 1 copy will show up in Context mode, but if you set it to Remaining Contexts, you should see all of them (or that was my experience, at least). If you don't actually get something assigned to the duplicate contexts, then they won't show up in the list, it seems.

So, go to Context mode, select All Contexts as the sidebar selector. You should see all of your contexts, duplicates and all. Select one of the duplicates and rename it slightly (put "keep" at the end of the name, for example). Now select the other duplicates in the sidebar, which should show you just the actions that you assigned to them, if any. Edit->Select All will select all of those actions, then use the Inspector or right/ctrl-click to get the contextual menu and set the context to the newly renamed context. Now they should all be using just one context (if they weren't already), and you can remove the duplicates by deleting them from the sidebar. Rename the context you kept, as desired.
