Lost some contacts

It seems I lost some of my contacts. For example I am connected with and listed on but I don't have it in my contact list anymore. Has anybody noticed something like that elsewhere?

The problem also is, that I am not able to re-connect because from the view of the profile I am already connected.

@Friendica Developers The contact itself is in my contects table. But it is not shown in my contacts page and is not autocompleted anymore.
