Sprite camera distance culling in niagara not working - 4.27.2

Hi guys, i’ve been trying to get sprite camera distance culling to work in niagara on 4.27.2 but it seems to have no effect. I’ve tried multiple different projects , systems , example systems but nothing seems to cull the particles. I’ve re-installed ue4 , installed ue5 and its works fine in ue5.
If anyone has any ideas on where I go next, ive tried everything i can think of.
Many thanks

Same issue, the particles don’t disappear when I get further away, even when going well beyond 1000 units.
