Cannot Import Content Blocking Firewall Rules

Running 8.3.0.5229 Max BR1 Pro
I cannot import “Content Blocking” firewall rules. So far all the other firewall rules transfer such as “Access Rules” but “Content Content Blocking” does not (see pics)

following up on this if anyone has noticed this issue.
Also, how do you “only” export firewall rules?? There is an import tab, just no export :slight_smile:

anyone from peplink seen this before?

Just updated a NOS Balance 30 Pro from whatever version was on it (7…x) to 8.3 - updating for each major branch along the way - and this is what I see as well. There is no categorical content blocking available like there is in my Surf Soho (which I mainly used to block Adware). There are only the “customize” options.
