TeamInbox Rules : Tags actions

TeamInbox Rules : Tags actions

Hello,
I'm taking TeamInbox in hand.
Sorry if i'm wrong, rules are heavy to manage (beacause of an issue ?).
After many test it's apear that : if actions to perform are multiple and one can't be done, any actions ocurres.

For exemple : Adding a tag witch is allready Taged or Clear a tag witch has not been used, makes all others actions dead actions, as usless rules.

It's so sad :/
