At the project level you have set default outputs to both Bome MIDI Translator 1 Virtual Out (the real port) and its alias "Bome Virtual Port 1 - Bome Virtual Port 1 -> Bome MIDI Translator 1 Virtual Out".
The second is an alias for the first so it sends it twice. Once to the alias which sends to the actual port, and another timer to the actual port.
Simply uncheck one or the other.

Yeah, the reason I found it so quickly is because I’ve been there and done that way too many times. After a while, you get used to looking for this stuff. Glad I could help!
