Citi Credit Card with Shared Limit Migrated to UB

I have Citi Rewards and Citi Simplicity na shared limit. After migration to UB, namigrate sila to 2 separate cards din and expected ko na shared limit pa din sila. Pero pagcheck ko today, seems nahiwalay na din credit limit nila? (dapat same available credit limit sila diba kahit 1 card lang pinaggamitan mo. pero sa case ko, they have different available limit). May naka encounter din po ba nito? Trying to check other posts with same situation, pero wala ako makita. TY
