Didn't receiving same amount of BAT as shown in Earning

Please answer my query I am quite confused
Since I am seeing more amount of BAT in my earning but not getting that much amount of BAT. This problem is with from 2 -3 months . Every month I get certain number of BAT’s but not fully getting .

For example if my earning is showing 2.685 BAT
then here I am only receiving 0.973 BAT

Please answer my question it is my humble request

Thankyou…
