OHIF Viewer not displaying patient's age in the patient details for some DICOM images

Hi,

I have questions regarding the OHIF viewer. Any help will be appreciated.
Below are the queries:

  1. Some of the patient’s DOB are not visible in the OHIF viewer patient’s detail section even though the DICOM image contains the patient’s Date of birth and is also visible in the Orthanc server. Please look at the attached pics for references

  2. By using OrthancAPI I’m able to alter the Patient’s details like name, date of birth, sex, etc. The updated patient detail gets reflected in the OHIF viewer like name, sex, etc but not the age. Please look at the attached pics for references

OHIF Viewer version: 3.3
