Data downloading strangely from Facebook

I have a query that's pulling:

Dimensions = ["Yearmonth","gender","age"]

Metrics = ["page_fans"]

I set up this report to update automatically every night and it's been working fine until last night. Now, instead of gender and age, I get one column next to the date with values in the following format:

0:4

0:5

0:6

0:7

The page likes and date do still download. 

Why is this happening and how soon can it be fixed?
