Codecov report is not correctly

In github,I submit a pr, but I change pr several times so One pr has many commitids .
Every commit submit a coverage report to codecov,but in codecov I cannot find the newest commitid's report .
And in github,  the codecov comment in pr show the  codecov report is old commitid's report.
When I submit report ,I sumit commitid info such as

bash <(curl -s -t ${token} -f ${report} -P ${PULL_NUMBER} -b ${BUILD_ID} -C ${PULL_PULL_SHA} -N ${PULL_BASE_SHA}
Please help me to resolve this problem,thank you very much!
