Nemesis Hinder status effect not working properly

Zynox

With the new update and changes to Nemesis, his tentacle hit infections are supposed to apply a 20% hinder effect for 2 seconds, and with the licker's tongue addon added it's supposed to be a 20% hinder for 5 seconds.

But when testing this out ingame, the survivors are barely hindered at all and get the same amount of distance from the speed boost. here's a video showing this issue:

I really hope this gets fixed soon in a hotfix patch or something.
