You wrote TELIA but your screenshot shows ARELION.
Here is mine from Arelion:

Notice Arelion dump my traffic to HE as well on the exact same router. Latency okay.
Everything else is blinded from MPLS circuit, shortcut straight to the BNG.
But this is a different problem from your Singapore egress. That one is because it route to France.

Last update to IP routing table: 4d10h23m33s
From here, you can see path 1 is chosen BUT the optimal path is actually path 4!
So bring this up to HE.
Finally, I want to stress that you must separate your problem down to individual endpoint. You see HE, you lump them all into one problem. In reality they are distinct problem with a different root cause.
my screenshot test all is using AWS EAST region itself, not any third party ip transit result. Because each provider will have different router host and different BGP community connecting it cannot be same.Here is mine from Arelion:

So bring this up to HE.
Finally, I want to stress that you must separate your problem down to individual endpoint. You see HE, you lump them all into one problem. In reality they are distinct problem with a different root cause.
And above tested ip TM egress is using AS1299 not even using AS6939.
