The workaround is to use a new contract with the same service graph or for each contract we need also to apply a new service graph?
In the current scenario (picture bellow), we got 1 L3out provider and a mix of L3Out and internal EPG with NO ISSUES!
However, there 3 internal EPGs that that we found that if we apply to the same contract the issue apeard.
1x L3Out prov -> cons:14 L3Out + 10 Internal EPG
