My initial thought would be that even though it's a clone, it still has a unique reference identifier that is off. IE it's the "same" file, but it's not necessarily the "same" file.
Try retooling your connection to the database, possibly by renaming the clone and referencing it as a different name.
although you do show that it is still returning rows of a total found, and blank rows.
I would look into how the data is being parsed into the cells of those rows, maybe the reference is off there.
You say you cloned it... did you put any data in the clone? (Yes I can see the blank rows)
Is the filename identical?
Have you done a "refresh" ... perhaps it is cache.
I am assuming you haven't changed anything basic like the layout it uses or what is on that layout including field names.
try deleting your cookies...
