I never could get it to straighten up and fly right, but I did find this before I gave up on it...
1. On a PC, go to C: > Users > your user name > AppData (make sure hidden files are turned on if you don't see this folder) > Roaming > Adobe > Dreamweaver CC 2018 > your language > Configuration > Brackets > brackets.json
1a. On a Mac, this "should" be... (I don't have a Mac)
a. do a search for ~/Library/Application Support (make sure the ~ is there)
b. hit Go
c. next, go to Adobe > Dreamweaver CC 2018 > your language > Configuration > Brackets > brackets.json
2. (make a back-up first so you can go back if you goof) Open the file in something other than DW
3. If the option for closeBrackets doesn't already exist, add a comma to the last item on the list, then add the following to the end of the file, before the closing } ...
"closeBrackets": false,
You may also need a line for...
"autoCloseBraces":false,
and
"autoCloseQuotes":false,
3. Save and open DW
