Columbia doesn't want to waste any money. After XO they have good reason to believe that the album doesn't have any (pop/international) hits, so I can see why they're hesitant to push more singles. Pepcé invested in her own album so they probably get a much smaller share of each sale. For them it wouldn't be beneficial at all to throw resources at the project in vain.
In the end it's always about money.
