Hi subrina,
The 7* version is an very old raid boss card that always have been at 30 CP, from the first raid boss rotation where there was only 6* and 7* in the set. When we made the new 8* version, we decided not to increase the CP, this is not a bug but intentional. However, we may lower some 6* and 7*'s CP in the future to make the CP in the set more progressive as you suggested.
Best Regards,
