Doesn't respect .spelling file

[iamnewton]

I have a .spelling file at the root of my repo with a list of things in it. When I run the following it respects the .spelling file: npx mdspell -ran '**/*.md' '!**/node_modules/**/*.md' --en-us but it ignores the line in it to ignore the - CHANGELOG.md file

But when I try to add another exclusion such as npx mdspell -ran '**/*.md' '!CHANGELOG.md' '!**/node_modules/**/*.md' --en-us it doesn't work.
