Change video fps = unreadable video

[allelouia]

I'm trying to mux a dolby vision movie at 23.976 fps with audio tracks and subtitles at 24 fps. I changed the fps of the 2 video tracks (the main one and the Dolby Vision track), added the audio tracks with a delay, added the subtitles. The produced iso is not readable. A mediainfo on the m2ts file gives strange results (there is not all the usual info)

Video #1
ID                                       : 4113 (0x1011)
Menu ID                                  : 1 (0x1)
Format                                   : HEVC
Format/Info                              : High Efficiency Video Coding
Codec ID                                 : 36
Duration                                 : 2 h 24 min

Video #2
ID                                       : 4117 (0x1015)
Menu ID                                  : 1 (0x1)
Format                                   : HEVC
Format/Info                              : High Efficiency Video Coding
Codec ID                                 : 36
Duration                                 : 2 h 24 min

If I leave the fps of the video at 23.976, the film is readable but of course the audio shifts compared to the video. So something goes wrong when you change the fps of the video.
