It's not a major bug :)

Yes, I see.
Problem is that I cannot fix it better than it is right now as it is a thirad party component which has limited configuration options.

I know, noit a problem. But
Why not leave it open, or set it to acknowlegemnt : "Wait for kuena" fix ?

Because it is not a Kunena problem, instead it is a third party component. I don't see a settings for this any time soon - so it is not a bug.
More like a feature limitation but not worth the effort.

I see you don't put link to manual a lot on forum ..... sometimes, it awfull ;)
