Rgb leds glitching

[Tangrowl]

I was using the asrock polychrome app and suddenly my rgb fans started glitching and i got an error, 

I have a asrock b450m steel legend motherboard and a deepcool castle 240 rgb.

The leds are flashing in a different colour.

There are 254 different things which i dont know what they are but before there were 10 of them.

The glitch occured when i was decreasing the Addressable led number.
