Dialog normalization removal in DTS-HD Master Audio

There is a DTS-HD MA 5.1 track (24 bit) with dialog normalization on both the master track and the embedded core track. I have uploaded the sample to your FTP server. Using the MkvToolNix GUI to mux an mkv while selecting the option to 'remove dialog normalization gain' from the track. The resulting file has dialnorm removed from the core track, but it remains on the master track. If possible, please investigate this issue. Many thanks.
