Drug hierarchy in ATLAS not matching ATHENA hierarchy

Dear all,

I am not sure about other domains but the hierarchy browser in ATLAS for the drug domain is somewhat different from ATHENA.

Here are some examples:

I’ve posted a similar issue here and I’ve noticed that this is an ongoing issue at GitHub.

I am still new to SQL queries so I would really appreciate it if anyone could explain to me the logic behind ATLAS’ hierarchy retrieval so that I can better understand the results shown in ATLAS.

Thanks in advance!
