Coverage not showed for manual PR analysis in Drone CI

I am running an analysis on Drone CI whenever a PR is raised.
Running the following command in drone sonar-scanner -Dsonar.login=$SONAR_LOGIN -Dsonar.host.url=$SONAR_HOST -Dsonar.pullrequest.key=${DRONE_PULL_REQUEST} -Dsonar.pullrequest.branch=${DRONE_SOURCE_BRANCH} -Dsonar.pullrequest.base=${DRONE_TARGET_BRANCH} -Dsonar.pullrequest.provider=github -X gives me this result:

If i run this on my machine the result is the following.

There seems to be an issue on how Drone checkouts the branch/PR, because I cannot find any other issues, the log of sonar-scanner on drone does not give me any warning.
