The EFL apologised in a statement for "a number of third party technical issues" during the coverage of the draw for the tournament, which has been re-branded the Carabao Cup.
"There were inaccuracies as a result of human error in the live graphics output, which resulted in confusion and incorrect ties being displayed on screen," EFL said in a statement.
