Need help with amenome

Hello, this is my first post because I'm having a small problem with Anemone.

When I launch the application, I can scan QR codes for themes, and I've even downloaded themes directly to my SD card, but when I try to press A to install a theme, it takes me straight back.

I've attached a pic so you can see what's happening.

Basically, the menu that appears on my screen when I press A (photo one) only works if I keep pressing the A button. If I release it, it goes back. (photo two)

If anyone has anh information, I'd be very grateful.🙏😭
