For imported services we need to reverse charge on different accounts.

Hello @mulder
Although I’m placing this into bugs, but it’s not as bad as you may think 
You can clearly see that the View and Transaction Journal screens both show the correct accounting treatment.

Thanks for testing and confirming the bug.
Total is wrong when disabling Amounts are tax inclusive .
Hence enabling Amounts are tax inclusive can be a workaround.
