There is a gap in the name history of this company. I am finding such problems quite often:
WebCheck says it was named “KENSINGTON GROUP PLC” from 11-Dec-1998 to 16-Jan-2015, when it changed to its current name. That omits that it became a private company and was named “KENSINGTON GROUP LIMITED” from 16-Jan-2015 to 31-Dec-2015, when it took its current name.
But the CH Beta says that it was called “KENSINGTON GROUP LIMITED” from 16-Jan-2015 to 31-Dec-2015 (which is correct), and omits that it was named “KENSINGTON GROUP PLC” from 11-Dec-1998 to 16-Jan-2015. During that period, it appears on CH Beta to have no name at all!
