Marker removed when component unmounts ( issue on iOS only ) react-native-maps

I am using the marker in my map like this:

<MapView            ref={map => (this.map = map)}            initialRegion={{                latitude: 37.78825,                longitude: -122.4324,                latitudeDelta: 0.0922,                longitudeDelta: 0.0421            }}            provider={PROVIDER_GOOGLE}            showsCompass={false}><Marker                image={imagePath.pin}                coordinate={currentLatLong}                title={formattedAddress}                draggable                tracksViewChanges={false}                onDragEnd={this.onDragEnd}                onPress={(e) => { e.stopPropagation(); this.onMarkerPress(); }}                zIndex={100}            /></MapView>

But whenever I move to the next screen and then go back the marker disappears completely, it works fine on android but not on iOS.Any insights?
