Music Band Pro -Blog "more" "older Post" button issue

Hey guys - On my blog page, there are 2 buttons after the last displayed blog post. The buttons are "load more" and "older posts" I only need to have one of these displayed so questions are where do I remove the second button / rename it? Also when you do load more, multiple articles repeat. You see the same as the first 4. How do we fix this? Thanks.
