Airspace Structure; Human Factors; Procedure
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.
[Report narrative contained no additional information.]
EUG TRACON Controller reported being distracted by a data block on the wrong target and failed to realize traffic he thought was a departure was conducting a Missed Approach. Controller allowed it to fly below the Minimum Vectoring Altitude.
