This is kind of a chicken-and-egg discussion. The problem is either or both (or more of one than the other) for
JomSocial and
Kunena. Obviously
JomSocial has a reputation to maintain (in the sense that their software interacts seamlessly with other Joomla extensions) or they might prefer that other Joomla extensions (e.g.
Kunena) should do the work so that they can offer their products as "
JomSocial-compatible". That then begs the question, well, if it's
JomSocial-compatible then can't it be also
Community Builder-compatible, and Brand-X compatible and so the list goes on. Ultimately it becomes an overwhelming problem for the developers of one Joomla extension to make their product interoperate with every other product on the market.
The issues that should not be in dispute are that
JomSocial is good for running certain things and
Kunena is good for running other things. If you want to manage your
Kunena forum use effectively then you need
Kunena software to do that (e.g. you cannot, for example assign a user to be a forum moderator with
JomSocial, you cannot assign forum ranks in
Kunena using anything other than
Kunena software).
Just as there is a problem with the gender value in
JomSocial not "taking" in
Kunena, there's also a problem that the Kunena forum signature cannot be set in
JomSocial. Likewise, you cannot change the preference first-post-first vs last-post-first in
Community Builder, either. To do these things effectively, you need to be able to change your
Kunena profile. Although it's possible, in
Kunena, to set
Community Builder or
JomSocial when people click a user's avatar or click the Profile menu tab, if they can't also edit their
Kunena profile (somehow) then they won't be able to change certain things (e.g. gender) as you have discovered.
I'll be honest with you. In my websites where I have installed Kunena (and I've used
Community Builder) I set the Integration »
Profile = Kunena in the
Forum Configuration. It's less hassle that way. I'm not trying to have an argument with your choice; I'm saying, instead, that I'm very sympathetic to the problem.
So, in conclusion, it would be nice to find an answer for you and, I think, it needs to be addressed by the
Kunena development team if they feel that this is a priority. In the meantime you have other ways of addressing the problem (either by hiding the icon or by accepting the fact that no Joomla extension is totally geared to work with any other Joomla extension ... no matter how much we'd like them to be.
The problem, actually, is easily solved by giving your users a menu item that says "change your
forum user preferences". But, I agree, that's a bit of double handling, isn't it?
I'll pass along your request for investigation into this matter. Cheers
