    Those values looked all fine to me so this variant is correctly marked as PASS. 

    Looking at your filters 

    QD = 5.09 which is greater than 2.0 --> PASSED
    FS = 0.0 which is less than  60.0 --> PASSED
    MQ = 56.10 greater than 40 --> PASSED
    SOR = 0.446 which is less than 4.0 --> PASSED
    MQRankSum = -1.981 which is greater than  -12.5 --> PASSED

    so on..

    Those filters are designed to tag variants with extreme biasses for those terms and values are derived from VQSR profiles that we had in the past. They are good suggestions to begin with but if you have reservations for more filters then you may need to experiment with those values and see how it fares. 

    Regards.
