Don't add extra spaces (x2) when encrypt

[anutator]

When I encrypt yaml file I get 4 spaces instead of 2 spaces and 8 spaces instead of 4 spaces. I'd like to work as before encrypting.
sops 3.7.3, Age 1.1.1, Linux (Ubuntu), vim editor. Is it problem of SOPS or age? Example:

Original

secretEnv:
  MAILER_DSN: mypass1

secretTiers:
  DIRECTUM_SOAP_SERVER_PASSWORD:
    _default: passexample1
    prod: passexample2
...

After encryption

secretEnv:
    MAILER_DSN: ENC[AES256_GCM,data:e2WdQdBlQoDxJ43iBOVTWrwun/AY6IwbGTA1aUH6HUbXFGzVnPb3W6GtytGaEJUZPJZb6E1lUyjE7ktWo6+MFA==,iv:Xh8PkXBCjA2Owr+2/lWt33MdHA5c8xWKyqaLOZKTTDo=,tag:hRJKsZQf3fxuO1NmsfE5Rw==,type:str]

secretTiers:

    DIRECTUM_SOAP_SERVER_PASSWORD:

I'm confident that if you encrypt a file using age, and then decrypt it again, the contents will be the exact same. There is something else in your pipeline that alters the indentation, or something with your setup for viewing the result that displays it differently.

Assuming msg.txt contains your message, the following will do a encrypt--decrypt round-trip and output the same message.

age-keygen -o id
age --encrypt -a -r $(age-keygen -y ./id) -o encrypted msg.txt
age --decrypt -i ./id encrypted
