This is most likely due to the service being new.  Whenever a new service is released, the cost will automatically go into the "Other" service category.

Brand new services are often not revealed to CloudHealth until after they are introduced into billing statements.  Any new service that is not recognized will be placed in the "Other" service item in reporting until our engineering team is able to create and assign it into its own category.  This process may take several weeks to complete based on prioritization but you can look at the dropdown details for the "Other" category to get a more granular view into the associated charges.
