Lifeline and Duplicate Legends Issue

So earlier today, I landed in Airbase and spotted a Lifeline running into one of the dropships near the cliff next to the zipline and started to punch her (as Claustic). This Lifeline had a body armor, level 1, which would mean her HP + shield should of been 150, due to the fact that I saw her land and she wasn't shot at. However, I somehow killed them with my fists, dealing less damage, which was 127 damage. I know she takes 5% more damage, but I hit her 4 times, each punch is 30 right? (Which 5% is 0.05 x 30 = 31.5 x 4 punches = 126, if that's the correct math, then Lifeline should still be alive and also it's off)

Also, I'll attach a picture of a later match where the champion squad had two Mirages. Unsure if they were cheating or not, so I'm covering their names.
