Title handling global Tag / Title

Hello,
I think i might found an issue with mkvmerge through command line.

I have a mkv file which have a global tag and Title. I use the following command line to remove title :
“C:\Program Files\MKVToolNix\mkvmerge.exe” -o “output” “File” --title “” --track-order 0:0,0:1

So i keep global tag and remove title : if i put the file in the gui of mkvtoolnix i can see there is no title anymore but with media info i keep seeing one title (1 guess because the title is also in the global tag)

If i put a new title with mkvtoolnix then I get 2 titles with mediainfo : Title 1 / Title 2

So is it possible that mkvmerge check the content of global tag and remove title in case of --title “”. Does it make sense ? How to choose a new title and put it with mkvtoolinix without having Title 1 / Title 2 ?

That’s not a bug. The --title option intentionally only works on the segment header field, not on tags.

Use MKVToolNix to remove and add Global Tags
And this… Enjoy!
