I am pulling data from Microsoft ads API for KeywordPerformanceReportRequest. I always have only 0.0 values in spend, but clicks and impressions are the same as in UI. There is no filter in the code for sure. What could be a problem?

The report columns are:
report_columns.KeywordPerformanceReportColumn.append([
'Keyword',
'KeywordId',
'KeywordStatus',
'Spend',
'Clicks',
'Impressions',
'TimePeriod',
'AdGroupId',
'AdId',
'CampaignId',
'GoalType',
'DeviceOS',
'Network',
'DeviceType'
])
