How can I make a cell truly blank when doing a Power Query import from CSV?

I am importing data from a CSV file into Excel 2016 using Power Query. Cells that should be blank are not truly blank.

The columns I am having trouble with are formatted as "Data Type: Text". These columns contain a variety of information and some of the cells are blank. However , when I finalize the import and load the data, these cells are not truly blank.

For example cell H2 should be blank. If I put a function in I2 "=isblank(H2)" the result is "false". If I click on H2 an press the "DELETE" key, the result turns to "true". Also, If I just double click on H2, the result turns to "true".

I have a column formatted as "Data Type: Date", which also contains some blank cells. These cells show in the Query Editor preview as "null", and import correctly.

The blank cells in the source CSV are empty. Meaning it is one comma followed by another comma (,,). There is no space in between, no quotes, and no other characters. This is consistent across the entire CSV.

I'm sure the solution is simple, I just can't figure it out. Thanks.
