modelbox will hide when I use Redux Action to fetch async data with the prop named isOpen is False

1.the prop isOpen is init with False,
2.with Redux,react-native-thunk, wrap ModelBox to a common component which can be used by Other View,
3.use the method open() to make the modelBox component to be visible,I can see the isOpen (this.state.isOpen) is True.
4.in ModelBox, use thunk to launch an async request to fetch remote data,but now the box is invisible automatically,and the **(this.state.isOpen) is False again.
5.but when I set the prop isOpen init with True,to do the 2-3 step,the (this.state.isOpen) is
still True,and the modalBox is always visible.
I don't want it to be invisible when I use redux and thunk to fetch async data,how to do?

Start by reproducing the described flow: open ModelBox, then use Redux and react-native-thunk to fetch remote data asynchronously. Inspect how ModelBox handles its isOpen prop and state during that update; done when the box remains visible after the request begins, with the behavior covered by a reproducible test or example.
