IP and blacklist

Hi,
I just updated WP Cerber on my 3 websites to the most recent version 6.0. They way I use the blacklist is, if I find a blocked IP address on the activity list, I add not just the single IP address but the IP network to the blacklist, if possible.

The issues I have now:
1) clicking on the IP adress in the activity list I still do get the two options offered – but clicking on “add network” does not work, just “add IP” adds the IP to the blacklist
2) in the activity list I see a lot of IP addresses I added to the blacklist in the past, but now not being marked. An example: I added in the past IP range 185.86.167.0 – …255 to the blacklist. The IP shown on the activity list is 185.86.167.4, which was marked in Cerber 5.9. Since the update to Cerber 6.0 it is not marked any more.

kind regards
