Your body stores fat where it has his Adipocytes, and it's easy that u have more around some areas. Also, there are some studies that shows some local fat lose, but for my experience after u also get more fat there, it's like that muscle claims for more energy so substances.
The best advice I could offer is, don't worry just keep cutting, finally u'll see all shape, just keep cutting. Probably u'll see before your lower abds than the shredded glutes, that point really use to be the last one...
