Why won't snippets choices display when i right click?

I have created a number of snippets, so it is important to see these choices available when i right click. However I am growing very frustrated that after one or two uses the my snippet choices disappear and I have to reload then, wait 30 seconds and hope they come back. Does anybody know why this keeps happening and how i can fix it?

Hi Andrew,

Sorry to hear you're experiencing issues. Have you tried uninstalling and reinstalling the extension? That usually does the trick.
