Jaxman Triple with mnt 17DDm driver and blf x6 driver, problem or normal?

So, I have assembled a couple of jaxman triples. I used the noctigon 3xp with 3 xp-l hi leds and some with the mnt 17ddm driver and others with the blf x6 driver.

From what I understand, the moonlight mode and the low mode are controlled by the 7135. The higher modes are direct drive.

My problem (if it is a problem) is that when I use any mode higher that the low I get a drop in luminosity very fast. So for instance when using the immediately higher mode after low, so the lowest DD mode, I get a drop in luminosity in 30 secs. That is with a LG HG2 battery fully charged.

Is that normal?

Update: I disable the thermal calibration feature and it seems to work fine now.

Sorry I am new to this.
