Answering almost a year later...
This was a particularly hard launch for JSPOC to track. The systems, processes, databases, etc are not well set up for a launch with a hundred+ objects.
It looks like a year later, 43822 still shows up as Object BS, and there are several other equally unidentified objects: Object X (43779), Object BE (43810), and others. This is true both on Celestrak and space-track as well websites that derive TLEs from them such as N2YO.com
Jonathan McDowell's Launch Log has 43822 listed as "VisionCube". Interestingly for VisionCube the Nanosat Database claims that no signal was received, and states that they are not even sure it actually launched. VisionCube is a 2U satellite from South Korea. Jonathan often gets information from other sources beyond space-track/celestrak. I don't know if the assignment of 43822 to VisionCube was insider information or a guess.
SatNogs, the open source ground station network shows "VisionCube" as active, although it only has 4 "successful" contacts since launch, so it is questionable whether they are actually tracking it. My guess is that it is an error in the entry because 1) they have it as catalog number 99930, which is not a real catalog number and 2) it is shown in a mid inclination orbit rather than the sun-sync orbit it should be in. If SatNogs is not using a real catalog number, I'm not sure where they would be getting their TLEs for tracking from.
Several places have the web site for VisionCube as: http://control.kau.ac.kr/visioncube/visioncube-2/
However it fails to load for me.
Bottom line - the JSPOC has limited ability to know which satellite is which, especially on these multi CubeSat launches. A 2U Cubesat will look like another 2U Cubesat on radar and optical. No way for them to differentiate. As a result they will sometimes leave objects as unidentified, and other times take a best guess based on something. Unless the actual operators post specific information identifying their satellite, these guesses go uncorrected. And of course, for the operators to identify their satellite, it needs to be alive!
I personally had a Cubesat on one of the first big multi launches, the ORS-3 launch back in 2013. At the time, it broke the record for number of satellites on one rocket, although the new record stood for only a few weeks. My 1U satellite, TJ3Sat from Thomas Jefferson High School was in the same deployer as Black Night, also a 1 U, from West Point. Neither satellite was ever heard from. Yet a few months after launch, TJ3Sat was assigned 39385 and Black Knight 39398. Both satellites in the same deployer, both 1U, both silent. I don't see how JSPOC would have been able to tell them apart, but somehow they each got a catalog number. That launch had 8 or 9 dead satellites, and I'm guessing at some point they just did a random assignment of dead satellites to unknown objects. But that is just a guess.
