even if we fix the panic in adjust, the behaviour is not expected

loaders:
  global:

this will add a config that has 0 pool-size, and "" dir. Maybe user is expecting two default values?

PTAL @sunzhaoyang

If a configuration item is filled in, press the filled value; if not filled in, press the default value, there should be no 0 or “”.
