Stucked in OmniBridge // Waiting for validator

More than one month ago I’ve sent xTRAC from x-Dai chain to Ethereum Mainnet over the OmniBridge. There seem to be an issue with the bridge. AMB Live Monitor it’s stated that there are only 4 of 7 confirmations. I checked my wallets. They never arrived in my Metamask, but they are also not on x-Dai chain anymore. AMB Live Monitor stated:

Status:
Manual execution waiting
The specified transaction was included in a block and the validators collected signatures.
Now the manual user action is required to complete message execution.
