Strange Buy Price To Ask Price Ratio Found In Btc Histrorical Quotes ( Roughly A 15% Difference )

I was doing some testing with historical Bitcoin prices, and stumbled across a few outliers in asking price. Here is the initial quote I found:

"t": "2021-10-02T07:00:00.855Z",
"x": "ERSX",
"bp": 47674.55,
"bs": 1.5684,
"ap": 56276.42,
"as": 0.0017

As you can see there is an unusual difference between the asking price and bidding price, roughly 15.3%. This is a very rare occurrence, however I wanted to report it either to be informed on what may be happening in this case, or to report a possible bad quote. In addition there are other quotes in that same minute with exactly this asking price. Here they are:
