Delta Not Consistent

[aekanshd]

Hello, we've just started consuming the API and everything was fine. From midnight, the delta has stopped showing. I saw the data.json and it turns out the statewise "total" delta is empty. Instead, now it's shown in "keyvalues". Why this change?

"key_values": [
		{
			"confirmeddelta": "0",
			"counterforautotimeupdate": "645",
			"deceaseddelta": "1",
			"lastupdatedtime": "31/03/2020 09:07:24",
			"recovereddelta": "1",
			"statesdelta": "0"
		}
	],
	"statewise": [
		{
			"active": "1165",
			"confirmed": "1347",
			"deaths": "44",
			"delta": {
				"active": 0, 
				"confirmed": 0, 
				"deaths": 0, 
				"recovered": 0 
			},
			"lastupdatedtime": "31/03/2020 09:07:24",
			"recovered": "138",
			"state": "Total"
		},
