I was looking at ads level data in the UI, segmented by conversion actions.
I saw that for one of the conversion actions, that was included in the calculation of both 'Conversions' and 'All Conversions' metrics, the numbers did not match between these columns.
In the attached images you'll be able to see that for the same conversion action (Web_sign_up), that is included both in All Conversions and Conversions, there are different numbers in each column:
For the same ad_id and dates, in the Conversions column I see a count of 107 sign ups, however, In All Conversions - I see 133 sign ups.
In the image 'conversion actions' you can see the ad I was referring to, and in the last row, you can see the values of Conversions and All Conv for Web_sign_up.
In the image 'list_conversion_actions' you can see the list of all conversion actions.
Could you help me figure out what is the cause of these different values?
