Kunena 3.0 + CB 1.9 + Joomla 3.1.1 : Signature Lost

Hello.

Actually, we have a web site running with :
- Joomla 1.5.26
- CB 1.2.2
- Kunena 1.5.9

All are deprecated and we are upgrading them on a new server.

So, our new server is running :
- Joomla 3.1.1
- CB 1.9
- Kunena 3.0.0

On our old server, signatures were hosted in CB tables :

Kunena is set as forum integration in CB -> Plugin -> Forum integration :

When I look into MySQL tables :

jos_fb_users : signature field is empty for my user
jos_comprofiler : fbsignature field contains my displayed signature

Now, on our new server, we have done the same for Kunena integration :

My signature is stored in jonk_comprofiler.fbsignature but when I'm logged on the forum, the displayed signature is the one stored in jonk_kunena_users.signature

So how can I set up CB and / or Kunena to display the signature stored in CB table and not in Kunena table ?

Thanks a lot for your help.

Here is my configuration report :

Database collation check: jonk_kunena_version have wrong collation of type latin1_swedish_ci on field version jonk_kunena_version have wrong collation of type latin1_swedish_ci on field build jonk_kunena_version have wrong collation of type latin1_swedish_ci on field versionname jonk_kunena_version have wrong collation of type latin1_swedish_ci on field state
