Apart from that, there is an issue with Performance plugin (version 1.12 and 1.13). Due to that, the LastReport (image doesn't show) and other reports are showing missing info.
To fix it, either you can download/git clone the latest code from Performance Plugin github repo and build it locally (using mvn clean install and you'll get performance.hpi Jenkins plugin file) OR revert back to Performance plugin 1.11 version.
As 1.12/1.13 have some other enhancements over 1.11, I selected to build myself, until someone will fix Performance Plugin and come up with a recent release version (aka 1.14 containing the fix for this issue).
