BLF17DD lost its modes

I was trying my triple XP-L EE X6 and suddenly noticed the BLF17DD wouldn’t change modes. I have to click really really fast 10-15 times to make it work. A normal click just stays in the same mode.

The driver is new and it worked for about 20 minutes before losing the modes. It is the double sided old model BLf17DD.

I took it out and tested it with a single led and the problem remains, any clue?

Blown capacitor maybe?
