User group can endorse several times a same proposal

Hi everyone, 1. What went wrong? After endorsing a proposal on Metadecidim, @virgile_deville and I realized both of us had endorsed the same proposal, with both our personal accounts and on behalf of our user group, @OSP. 2. What did you expect to happen? When two users of the same organization endorse/vote for the same proposal on behalf of the group, I expect the platform to take into account one vote/endorsement only. 3. Where did you found this bug (which site)? On Metadecidim Thank you!
