I'll bet if you look at your "all rows 2" indicator, it is probably empty, not what you'd expect from a .csv with 7000 entries.
You are making use of Express VIs, which are many times "not your friend". You have specified the file type as an "LVM" text file, but have named it as a .csv, which has a specific meaning ("Comma-Separated Variables", where NI likes to (by default) make them "Tab-Separated Variables", which is also not so bad. You are also using Dynamic Data Wires, which I've never liked, and are sending these data to the Dreaded DAQ Assistant (hmm, is my prejudice showing?).
If you really do have a .csv file, NI has a "Read Delimited Spreadsheet" function in the File Palette that should shlurp up tab or comma-delimited data (tabs/commas separate entries in a row, i.e. are column separators, and separate lines of text are rows, or Channels, if you are doing multi-channel DAQ stuff).
Where did the data (7000 readings) come from? You might consider showing us a sample of the data file (maybe not all 7000 readings, but enough that we "get the idea" of the data).
