There is a bug in the DHCP lease list in the RouterOS device setting tabs.
All DHCP leases are grayed out and show an X (disabled) in front of them, even though they are up and running on the devices.
Dude is 6.41.2 running on a CCR1009-7G-1C-1S+ (Can not check earlier versions since i just found it out after the last upgrade).
It affects all devices running a DHCP server on ROS in my network, not only a single one. On the SNMP tab, the DHCP lease list is always empty.
