Which Bisq version are you using ?  
Which OS ?

Bisq 8.0, Linux Fedora 29  
Last upgrade of Bisq/Fedora is both mre than a month ago, so no direct connection to a software change …  
Travelling, have the seed not with me to load it in another instance.  
When I start Bisq with another instance  
– appName=Bisq2  
then it starts normally, of course not with the funds of the other instance.  
Is it wise to delete the double transaction out of a file (if yes what file) or would I corrupt something then?

Thank you!

Go to **~/.local/share/Bisq** , there you will find all the files relevant to your Bisq installation.

Try to restore from one of the wallet backups from **btc\_mainnet/wallet/bisq\_BTC\_wallet/backup**. Just replace **btc\_mainnet/wallet/bisq\_BTC.wallet** with one of those files.

Eventually you will find a backup created before the duplicate transaction was introduced into the wallet.
