Non-optimal PoPs used

Hi, 

Just reaching out for someone to advise on what I can do to change the PoPs used by my connectivity. For some reason, it's using zepto-sin-1 when lightnode-mnl has lower ping. Is there a reason I'm not routed to lightnode or am I misunderstanding something?

Here's the link to my diagnostics: https://nextdns.io/diag/a13eb4c0-0635-11f0-aa9a-e39a64f67dff

Thanks.
