Is there anyone having this issue?

I create multiple criterias in my business rule and i save it

When i go to the business rules list, my new one doesn't have the criterias or maybe one or two !!

I tried t add them one by one saving in between, but there is no consistency ...

Not even an error message telling me my business rules have something wrong ... 

Just have to pray to see it saved the next time!

Thx,

Franck
