Should AgeRange/Gender reporting return UNSPECIFIED for age_range.type and gender.type

[Robert Mic]

Hello,

I am trying to use the beta API to fetch performance reports from campaigns using the following query:

```

 SELECT

 campaign.name,

 ad_group_criterion.age_range.type,

 metrics.clicks

 FROM age_range_view

```

The request goes through successfully and returns 7 rows per campaign as expected. However, the large majority of these rows report a `UNSPECIFIED` for the age range type. There are some rows that do show the expected type. I also tried setting up an equivalent report in the Ads UI, and that correctly reported clicks by age range.

I also tried doing the same but selecting from the `gender_view` resource (and fetching gender instead of age range on the criterion) and the same thing happened. Most rows are `UNSPECIFIED` when asked about their gender type, but some had the expected type.

Am I formatting my query correctly? Why do most rows get reported without an age range / gender type? Do we have to setup our campaigns in a specific way to get these types to properly report?

Thanks.
