Facebook Audience Network - very drop in payout

I checked pending payout in Facebook Audience this month and it is a big difference between value from payout tab and the performance tab. What could be the reason that so much has been deducted, approximately 30% deducted?
Can you see how you this month?

Yeah I see that in my console too…too much drop in Feb earnings…usually I get 5-10$ less …For Feb month it’s nearly 100$ for both of my accounts in payout tab…may be some glitch or invalid clicks…
