Blast mine is buggy if two survivors try to use them after each other

Sigee

When my teammate used blast mine on a generator, the killer kicked it and while the killer and I were blind, I put my blast mine into the same generator. The perk started to count down, so it should have been active. But when the killer kicked the generator again, my perk was deactivated without any effect (blind/stun), and the generator started regressing like there was no blast mine activated on the generator.
