When will the setting docstr-format-var property change to the new value?

[iT-Boyer]

The default value of the docstr-format-var property is "- %s:".

After this setting, but the value does not change to "- Parameter %s:"

(after! docstr
  (setq! docstr-desc-summary "[描述]")
  (setq! docstr-desc-param "[属性]")
  (setq! docstr-desc-return "[返回值]")
  (setq! docstr-format-var "- Parameter %s:")
  )
