Lost STAKE tokens on OmniBridge sending from xDai to Eth Mainnet

I sent STAKE from my xDai account thinking it would go to my Eth Mainnet. however when all 8 confirmations were done they were not transferred to my ETH mainnet.
Instead the are in a contract called EternalTokenProxy. Surely they can be sent back or to my ETH Mainnet.

Is there a way to get them back?

Thank you SK

In the telegram chat we agreed that you can finalize the token transfers through AMB Live Monitoring app: https://alm-xdai.herokuapp.com/. You could also try the new OB UI instead of ALM to claim your tokens. There is the History tab there which allows you to execute unclaimed transfers: OmniBridge.
