Narrative:

During training session on radar east we were getting pretty busy. Aircraft X was on a missed approach. I thought he was just a normal departure climbing to 5;000 feet. We had an aircraft's data block acquire on a VFR 1200 code target and was trying to fix this. While we were trying to fix the issue aircraft X flew into a 4;400 MVA at an altitude of 4;000.the main issue we had was an IFR data block acquired onto a VFR 1200 code target for some reason. This took our attention away from aircraft X and caused us to miss his altitude.
