Can't save settings with *.mtxcfg extention on linux
I use mkvtoolnix v51 and ubuntu 20.04. When i save a project i can't save is as <file_name>.mtxcfg. its saved as a normal file without file extension even when i select the file type in the 'save as' window. When opening a project file the file is not shown until i select the right file type.
I have this problems since i use linux 4 years ago. On windows 7 it worked without problems.
