Inferred path with (extra?) "drug x - Same as - chemical x" hop

[khanspers]

In the results from the query "What drugs may treat conditions related to Leukemia", one of the drugs returned is Anistreplase with several inferred paths. The first hop in one of the paths is "Anistreplase (drug) - Same as - Anistreplase (chemical)". I haven't seen this before, so I'm wondering if it's a bug that this is shown in the UI?

Drug: (https://go.drugbank.com/drugs/DB00029)
Chemical: https://www.ebi.ac.uk/chembl/compound_report_card/CHEMBL2108250/

It's coming from ARAX/DrugBank.

Will update this ticket if I find other examples.

looks like it's coming from ARAX, i'm not sure who to assign it to so asking @edeutsch to take a look

The current RTX-KG2 has some Drug - same_as - Chemical edges. Is that specifically disallowed?

In any case, the next RTX-KG2 in dev and CI no longer has these, so this will disappear in coming releases to TEST and PROD.
