Getting stranger, they are blocked again. According to the rule it should be suppressed but clearly it was blocked.
I now manually added the ips to the alias and did a "update - reload -all) and now it is working again.

So the alias "pfBlockerNGSuppress" was apparently the right place to add them, only when I added it from the reports it did not show up there and was not working again a little later
