phantom AMS after firmware update (X1c AMS and AMS2)

[haneo2025]

I've been running HA-bambulab 2.2.22 for a while, , to get some control on my X1c (firmware 1.08.02) and AMS1
I added an AMS2 last November, and awaited until the new firmware 01.11.02.00 was published end of mars to update the X1c and both AMS, to benefit of the drying feature.

since this update, I now see 5 devices instead of 4 previously, as my AMS1 now appears twice, one instance being "unknown" ,and without any entity :

Anyone has seen such situation ?
Any way to delete it ? it seems I can only disable the device

I thought I ask here before taking any drastc measure

thanks
