CHIRP

I have a problem with DUPLEX channels...
(I'm using CHIRP daily-20200807)
My Baofeng UV-5R+plus uses the FREQUENCY column as the TX frequency (and I need a +4.6 offset).
All Marine VHF channels and a lot of videos show instead CHIRP FREQUENCY field as the RX freq (and a -4.6 offset..)

How can I fix this without rewriting all frequencies ??

example:
POS 1, FREQUENCY 156.050, NAME: SEA 01, DUPLEX: +, OFFSET: 4.60000 WORKS
Instead:
POS 1, FREQUENCY 160.650, NAME: SEA 01, DUPLEX: -, OFFSET: 4.60000 DOESN'T WORK

When I say "Work", I means that I can TX and RX to/from a marine radio...

Thanks,
Alex
