[FFmpeg-user] MXF container tags modified when replacing audio

I use ffmpeg to replace audio streams in MXF containers, with -c:v option to leave video stream unchanged.
I thought that all MXF metadata and tags would be unchanged, but that's not the case and everything's is changed in the header.
Most of time it's not an issue, but in a particular case, the player can't read properly the file as the "Video Line Map" tag value is not what expected.
Is there a way to keep all MXF's header value unchanged ?
