Few DLP sensitive labels not working; ABA Routing number and Date of Birth(DOB)

The default DLP rule for ABA Routing Number will only trigger if there is a keyword within 300 characters of a 9 digit number. Otherwise without the proximity match, it would generate high false positive rates since any 9 digit number would trigger the rule. You can find definitions of what triggers a DLP rule here:
https://docs.microsoft.com/en-us/microsoft-365/compliance/what-the-sensitive-information-types-look-for?view=o365-worldwide

Regarding the Date of Birth, you need to create a custom DLP policy as described here: https://docs.microsoft.com/en-us/microsoft-365/compliance/custom-sensitive-info-types?view=o365-worldwide

Please try the ABA test again with one of these keywords within 300 characters of a 9 digit number. And send screen shots of your DLP Policy configuration.
