实例化时，Unity CanvasGroup的alpha设置为0

Question

我创建了一个内部装有CanvasGroup组件的预制件。当我实例化它时，即使在预制中将其alpha设置为1，它的alpha也变为0。

RemoteDiffMenu remoteDiffPrefab = Resources.Load<RemoteDiffMenu>("Prefabs/Utils/UI/RemoteDiff");
RemoteDiffMenu remoteDiff = Instantiate(remoteDiffPrefab, transform);

它是在另一个CanvasGroup下实例化的。

SettingsMenu和RemoteDiff都包含一个CanvasGroup
