ESSID regularly removed /reset

[PD0DIB]

Ok, something i've observed...
Have multiple hotspots (simplex and duplex), all with a unique ESSID.
All running 4.1.x Pi-Star on Raspberry.

Two if them are 'in production' (24/7), 2x duplex and 2x simplex are used for testing, mostly Nextion screens.
Therefore, I regulary switch off/on those hotspots.
I noticed one hotspot received a qso, the other ones did not (all same config and static TG's).
I noticed too it was the last switched on who did see traffic.
Took me some time, but I found out why...
Pi-Star did remove ESSID from all my (regularly switched on/off) hotspots, having multiple hotspots with the same ID (Standard DMR-ID, no ESSID), and the last switched-on was connected, others were not connected anymore as noted via Brandmeister dashboard.

Why? Don't know.
