Nanjg regulation fail

I have used nanjg 105c without mcu, to regulate a lot of 2*18650 6v led builds.
Today I tried to use the same setup on a HD2010.
I really dont know why but I face a regulation loss. Flashlight is working in dd.
Drivers are the following:

I have checked every possible short circuit of led- with flashlight body cathode.

In one of drivers, I am sure that I checked and was regulated, before I installed it in the flashlight.

Any ideas?

A 6V LED is 2 dies in series, right?
If memory serves from having 2 XMLs between the + of a 3S pack and the + contact of one of these drivers, and then another XML in the normal position (all XMLs had a Vf of 3.05V at 3A) the AMC chips will regulate until they overheat and then start cutting out to keep heat down.

I do horrible things to electronics in an effort to get them to do what I want.
