FUT039 instant blinking in all colors

I have bought and connected 3 controllers FUT039 through WL-BOX2. 2 of the controllers when connected with LED strip on start it flashed red, and after linking it blinked slowly red. But 1 of the controllers when I connect it is just flashing in all colors and I can’t link it at all. What can be the issue and how to fix it?

Best regards,
Mile

The led strip should blink green slowly while linking is done, it won’t blink red slowly, please check user manual and retry it.

I have the issue with the one that changes colors when plugged in. That one I am mot able to link, the others are linked and working properly.
