It said something about getting cancelled, but also said something about them getting MiGs and a few sorties as bomber escort.
If your resources contradicts itself then it's really not that good of a resource. No, the F-82 did not score any kills against any MiGs nor did they act as bomber escorts. The F-82's early mission was to provide air cover during the early days of the Korean War when the US/UN forces where in head long retreat down Korea and then as ground support and then later on doing night time interdiction missions until replaced by the B-26.
F-82s scored a total of 4 kills: Yak 11, Yak 9 and 2x La-7s.
