Can't view the lava information from android-build for some builds

Hi,

Just found that I can't view the lava result on android-build page for some build. but not all of them, I still can view some the information of some builds before. say the builds of https://android-build.linaro.org/builds/~linaro-android/snowball-jb-gcc47-ig.... For the build #28 even I click the " login to LAVA " link and logged in, I still get this information like the NG.png attachment file. But for the build #26, I can see the lava information listed. Like the attached OK.png file
