why DP value in FORMAT (sample DP, I call SNVs in one sample) is higher than DP value in INFO field?

I use haplotypecaller for SNV calling in my whole exome capture sequencing project, but I found some abnormal result in the output of haplotypecaller (version GATK 3.6).

It's abnormal to see the sample DP value is higher than DP value in INFO field, because the sample DP value is filtered coverage, but DP value in INFO field is the raw one.

Anyone can help me with this problem?

Thanks a lot.
