My heart just missed some beats.
After increasing the size of the subnet of one RED Device and then, because there was an existing static lease in the middle of the new available Net-Range, I decided to add an other dynamic range after that static entry.
After that, the DHCP Server on that object was first disabled automatically. At the same time, the RED List (24 pcs) on XG became empty except one device!
We're on XG430_WP02_SFOS 18.0.5 MR-5-Build586
I enabled the DHCP Server on the object again and it served IPs to the devices. So it looks like it is technically working.
But the RED list remained empty.
This DHCP config will cause all REDs ti disappear from the RED list on the XG:
This DHCP server config with only one dynamic Range will not cause REDs to disappear and will also "unhide" the previously disappeared REDs:
This is the exact issue as described here by Paulo Jose Bueno. I'm glad I found this as a proof. Phew!
How can this really be "This is not a bug this is as design"? This looks like a huge bug to me.
