Gun damage drop-off range displayed in UI with Sharpshooter is wrong

[Shrimp Wheeler]

Issue: buying sharpshooter in the shop in sandbox as yamato updates the new UI showing dropoff from "22>46" to "37-61"; it adds 15 meters instead of 15%. I haven't tested other characters but likely same issue I bet
To reproduce: Go in sandbox and check UI and buy sharpshooter

Just wanted to confirm that this also happens with other heroes too.
