[Theme: Simple Catch]

Hello – I’m in my very first few hours of updating my site, and I have 2 questions that I’m hoping you can help me with:
1. For some reason, my “blog” page has a completely different layout than the rest of my pages. I’m thinking this is because I accidentally installed WordPress twice. I tried to uninstall the second WordPress, so maybe it just takes a while to refresh and will be better in the morning. If not, is there a way to fix this?
2. I created a child theme for Simple Catch and am now using that. But when I look at the “WordPress Updates” page, it still asks me whether I want to update my Theme from Simple Catch 2.3.2 to 2.3.3. Do I want to do this, even though I’m running off of my Simple Catch child theme?
Thanks so much!
