While coming off A PREVIOUS flight I had flight ABC with 68 mins to load after I printed out the card. While working ABC the crew had 3 leads total. While loading the front another lead said I'm going to take care of the manual pit 51. I responded OK he continued to load the back. After completion of loading the cans; I tried closing the flight it wouldn't close so I went to the loading program. While at loading program; I still can't close the flight. I call load planner and we determine there isn't enough weight in pit 51 as I'm on the phone I noticed the plane went by and I called zone to let them know I need them to return to gate to add more weight. Apparently; they were calling me for weights on zone 1 but I was on channel X till the flight is closed out. I never authorized the plane to leave the gate. Also; when verifying the Hazmat; the scanner never showed pit 51 it showed the Hazmat in the forward cargo holds.
Ground employee reported an aircraft departed the with erroneous Hazmat cargo location; as well as incorrect weight and balance data.
