ARM64 build on Windows auto-updates to x86 builds

I have a Surface Laptop 7 with the Snapdragon X Elite CPU. I'm installing the ARM64 build of 1Password from the website. After install, I can validate this is indeed running as native ARM64 code with Task Manager.

Later, I noticed that as 1Password auto-updates, it replaces the ARM64 build with the x86/x64 build. When I look in Task Manager, I now see "x64" as the architecture. I am running the production channel. Has anyone else observed this behavior?
