bad node and bad edge for "[fr] commune"

[felix9]

http://www.conceptnet.io/a/[/r/Synonym/,/c/fr/commune/n/wn/animal/,/c/en/spotted_salamander/n/wn/animal/

This seems to be an error from Open Multilingual WordNet. "[fr] salamandre commune", which means "[en] common salamander", somehow became "[fr] commune" linked to "[en] salamander" in OMW, and it's considered a stronger edge than the connection from "[fr] commune" to "[en] common"

So... this is an isolated error, not a systematic error, but it's not clear to me that bad info like this can ever be "unlearned" by the system. Is there a mechanism for fixing bad data like this?
