MKV Tag Editor commands

I am having trouble with removing tags from MKV files. I can't figure out how to remove a comment/description tag with mkvpropedit, and Windows 10 says file access denied, that I need permission to edit the file, even though I am an administrator.

I found this other thread really helpful and I was able to remove the field called "Title" in Windows 10, aka "Movie name" in MediaInfo, using mkvpropedit

echo Changing %%m Title to "%%~nm"
"C:\Program Files (x86)\MKVToolNix\mkvpropedit" "%%m" -e info -s title="%%~nm"
echo -----
)
echo ***** Finished *****

I just changed the line of the batch script to put a blank string for the title/name

Code:

"C:\Program Files\MKVToolNix\mkvpropedit" "%%m" -e info -s title=""

But the "Comments" field in Windows 10, aka "Description" in MediaInfo, has been difficult for me to figure out how to remove.

I used the MKVToolNix mkvinfo-gui.exe to show all the elements, and I found the tag I'd like to remove in certain location with the name: DESCRIPTION

the elements listed were

EBML head
Segment

Seek head

Segment information

EbmlVoid

Segment tracks

Tags

Tag

Targets

(note: nothing is listed under targets, no track UID or anything)

Simple

Name: DESCRIPTION

String: <this is the string I want to get rid of, or the whole tag>

Cluster

...

Cluster

Cues

but I don't know how to edit or remove that tag. The mkvpropedit commands are not clear to me on how to do this. This particular tag/field does not show up in the MKVToolNix GUI header editor section either

any help would be appreciated. Thanks.
