Jitsi Desktop: Correct online status only for the first 5 contacts


in the contact list o my SIP-account I have two groups with each about 10 contacts. The correct status is only shown for the first five contacts in the first group. If I rename the contact groups to have a different order, after restart of Jitsi desktop again only the status of the first 5 contacts are shown correctly, all contacts below are shown offline, althoug they are online indeed.

If I add another contact, it shows the correct status until restart of Jitsi. If I add 10 more contacts, they all show the right status until restart of Jitsi.

My collegues experience the same strange behaviour, the only difference is, that one of them gets 6 correct status. What can we do to solve this problem?

Thanks for your support
