Adding contacts to trusted senders not working (all is save under personal )

[Ronald75]

I have this problemn where users are unable to save contacts as trusted senders.

When I user tries to add a sender it gets saved under personal..
I have looked at display preferences and it is set to allow images from trusted senders.
Also in config.inc.php I have setup $config['show_images'] = 3;

Nothing works.. Is this a bug or am i just forgetting something?

Running Roundcube version: v1.6.14

what do they have set under Preferences > Contacts > Collected addresses > Store trusted senders in?

also how are they adding the trusted sender?
