pytest-cov not respecting the --cov flag

Expected vs actual result

I am expecting that the --cov flag directs which directory's(package's) coverage is to be calculated. I only want to calculate coverage for src.blueprints package of mine, whereas pytest-cov gives me the coverage for my src directory even after explicitly changing the --cov parameter to src.blueprints or src/blueprints

pytest -c config/pyproject.toml --cov src/blueprints

Config

Here is the pytest relevant section from my config

[tool.pytest.ini_options]
minversion = "6.0"
testpaths = "tests"
addopts = "--cov-append --cov-branch --strict-config --verbose --code-highlight yes --color yes --cov src --cov-report term"

Code

The code in question belongs to unofficialopensource-knit/email_service

I am getting the same response if I change the --cov flag in my config file and don't pass the flag explicitly on the command line
