Can't reinstall Pages, Keynote, Numbers
Due to some issues with my versions of command line tools, Python etc., I decided to reinstall macOS Sierra onto my Macbook Pro (2016 model with touchbar). But when I installed from the bootable USB, I ended up installing macOS High Sierra onto my machine. The OS is working for me but in this process, I realised I lost Pages, Numbers and Keynote from my mac. I read online that I could go to the App Store and reinstall these from my Purchases tab. But whenever I try to this, it shows me 'Pages failed to download. Use the purchases page to try again.' This keeps happening for all three whenever I try this, and my App Store purchases for these 3 now look permanently like they do in the photo attached.
I have no clue what to do about this, can someone please help?
