I have setup jenkins for Performance Test Execution so once script execution completed then after HTML performance Report is generated but after some build / job execution previous HTML report is detached from Jenkins dashboard.

see here, Test Report is showing for Build 14  but it is detached from build 11. it is also available in    \jobs\Client\jobs\XXXXXXXXX\builds\11.

same thing also showing in "Performance Trend" report. it is skipped Build 11 result from plotting. and directly jumping to 12  means it is showing only build - 10, 12, 13, 14 results.
