This might also be the issue. A lot of user are complaining about jaxx recently.
Most of them seem to be unable to send any funds (mostly connection issues).
This could be your problem too, it would explain why your balance got deducted first (jaxx trying to send funds) and
afterwards it appeared again (jaxx failed to connect to push tx(?)).
You can try to send your funds again (but make sure to include a high enough fee: https://bitcoinfees.earn.com/).
If you furthermore won't be able to send anything out from jaxx you can [1] export your private keys and [2] import them into another wallet (e.g. electrum).
