LED strip + sequential driver help

Hello

Not sure that this is a correct spot to post this to, but maybe somebody will react.

Issue is pretty much described in this video here: https://www.youtube.com/watch?v=F2jYBCzxvJk

Swapping driver and led strips didnt do the trick - first 3 leds of the bottom strip still went off instantly instead of going off sequentially like the one above it.

Any idea as in what to look for ?

That’s weird! I just watched that video you linked and I can’t think of anything that would make it do that. The LEDs come on just fine, but don’t fade out properly. I wish I could help you. Maybe someone will come along who can.
