White mode = 4 different device

Hello,

i'm using RGBW2 in white mode but in the app on my phone 4 devices are shown when i switched the RGBW2 from color to white mode.

Already tried to reset device, reset to factory, delete device, redo the room, nothing to do, the device appear 4 times in the app (and in the cloud).

The firmware section offer me to upload a beta firware. Why? My other RGBW2 don't do that and act like 1 singel device.

What can i do to solve?

Thank you for the quick answer.

I have 9 RGBW2 all setted in the same way, white mode, but only one is shown as 4 device, all running 1.8.3 firmware. So, do i have 8 faulty and 1 correct?

Why this single RGBW2 is prompting me for upgrading to a beta firmware?

All my 8 RGBW2 are showing this interface:

while the quadruple one is showing whis interface:

Why this?

So my only chance is to wait for a new firmware? No1 had a similar issue?
