No coverage information for some sites after BP RESOLUTION haplotype caller?

Dear GATK team,

We are trying to run GATK haplotype caller with BP RESOLUTION to get coverage information for each site. But it seems like some sites don't have any cov information, for example:
jcf7180012625382:4560 4560 . A G, 0.01 . MLEAC=0,0;MLEAF=NaN,NaN GT ./.

I wonder if it is because GATK is not sure about how to call this SNP because signal is too low, or there are some explanations can help me with this issue?

Thank you for the help!

    Would you be able to post the command that you used and the version that you are using to get this output?It does look like the QUAL score of this site is quite low which might be a reason that you are not able to see coverage information but more details of how you arrived at this record will help!
