Amazing. Please send me the file you used and I’ll figure it out. I suspect you are right, you do not want to include all the blank lines from Excel in the CSV file. Or, what do you know, they get read in to the database. (I can make that better, but let me have a look at your file and see what’s needed.)
If you go to the players screen. You can check all the players you wish to delete and use the bulk delete option at the top left. You can even select them all with one click. Then be sure and go back and EMPTY the TRASH, so all those bogus players are not hanging around.
