Suppress IPv6 in logfiles?

[c-mu]

Hi there,
my live view logging gets flooded with IPv6 entries - but I'm not interessted in it because I'm not using it on any interfaces. Is there a way to suppress those messages? It's hard to see the IPv4 Traffc there, have a look at the attachment.

Allow IPv6 is uncheck here: Firewall -> Settings -> Advanced.
No interface has an configured IPv6.

Thank you!
