This has come up a few times - we've not got to the bottom of quite what scenario causes it to get into this state.
ADE (L and XL) no longer have the old "analysis order" field - it's controlled by the order in ADE. You can bring up the test editor in ADE XL and then drag the order around. When I saw some data which had this problem, dragging the order around in the test editor fixed it - but didn't explain why it got into that state in the first place. You can't drag them around in ADE XL itself - you need to double click on the test name and fix it there.
