fbRads | manage Facebook ads from R

I'm using the fb_insightsfrom the package fbRads like this: (I use more metrics in my real problem)

fb_campaigns <- rbindlist(lapply(l, function(l) cbind(Campaign = l$campaign_name, rbindlist(l$actions))))

Oh, and I get some warnings (I know I'm doing something wrong, but can't solve it):

Warning messages: 1: In data.table::data.table(...) : Item 1 is of size 11 but maximum size is 104 (recycled leaving remainder of 5 items)

The result is the data frame with all the data I need (Campaign, action_type, value), but... the columns with the "action_types" and their numbers came out of order. The action data don't seem to be from the campaigns in the rows.

How can I merge the action types with the campaigns?

After I the data in the correct rows, I will use reshape to make the action_types columns with the values.

The data I get from fb Rads and I want to transform are like this:

The data I get using my code are like this (the format is OK, but not the order of the values, they are not the values for the campaigns)
