When you click the expand option in the upper right side of your 1st page screenshot ,the following expanded page is a new table page totally, you can convert the last two steps to find differences, and the NewIndex maybe one of the differences.

Step 5 Left join query, join the level table below
Step 6 Expanded Table, the index of the previous step of the data has changed
Since the index is added before, why is the order of the latter still changing? This will cause trouble for people. Later I found that if you add an index with a custom formula after sorting, the results displayed will be incorrect. If there is no sorting that starts first, the result of the last step is the same as the result of the step of indexing.
Expect: The result I expect is that what the eye sees is the desired result, and does not cause harm to others.
In addition: I don’t know how to attach test data, if you need I can send it by email.
