jos_users params gets larger every profile save?

Well, I guess this must be a non-issue.

Since hiding them any other way breaks the application - I set the params class to "display:none" within the template CSS to hide them from the front-end.

Not exactly an elegant solution, but the best I could come up with.

Thanks anyway.

I have the same problem I installed joomla 2.5.9 and the component CB 1.9 when I update profile in the frontend "Contact Info" the user table field params get like this:
{"0":"{\"admin_style\""\",\"admin_language\""\",\"language\""\",\"editor\""\",\"helpsite\""\",\"timezone\""\"}"}

But if I update in the backend the params field come back to :{"admin_style":"","admin_language":"","language":"","editor":"","helpsite":"","timezone":""}

There is something that I can configure or it's a bug?
