Savior Kill means not only destroying an attacking enemy - his target must be your squad member. Since hero modes don't have squad spawn, you don't have Savior bonus.
I suggest you finish it in Starfighter Assault before they actually mess up the whole thing with the upcoming new squad system... This milestone is a pain in the butt, though.
Two tips, never spawn alone as Tallie - you won't have anyone to save. Go back to the selection if the spawn timer is at its end and you're still alone. After spawn, follow one of your squadmates around, and take out anyone attacking him.
Alternatively, try playing with a friend who'll spawn as the Falcon while you spawn as Tallie. Takes a bit of preparation and luck - you both have to get enough BP and also a free hero slot, but if you can manage that, everyone will gang up on the Falcon and you'll get your savior kills.
That's how I did it anyway, though I only managed it through random Falcon spawns with me, so it was through a lot of active grinding. I don't even know why I bothered, lol.
The fact that the game never even told you what a Savior Kill means makes it worse aswell. The supposed "tutorial" mode should be exactly for things like this, instead they made an Arcade match and called it tutorial...
Sorry I couldn't be of more help - honestly, I don't think anyone will bother with a remedy for this. Actual bugs get ignored for months, it is really a sad state where the game is.
EA Staff (Retired)I'm sorry for the late reply 😞 It may not be a bug with a high priority, but I'm still going to send it to specialists for further investigation, so thank you for reporting this in the first place!
