$w.onReady(()=> {
	$w("#datasetOne").onReady(() => {
		$w('#datasetMyOne').refresh()
		.then(()=> { 
         	console.log("Done refreshing the dataset1");
         });
	});
	
	$w("#datasetTwo").onReady(() => {
		$w('#datasetMyTwo').refresh()
		.then(()=> { 
         	console.log("Done refreshing the dataset2");
         });
	});
});

Why do you use different IDs for the same DATASETs ???
Is it —> “datasetTwo”
Or is it —> " datasetMyTwo"
???
