Help How to delete the "not assigned" contacts on my phone?

[Chruseli]

Hi there,

I am new in this forum and have a question, maybe one of you can help me:

My phone Samsung GT-B5510 Android 2.3.6 has in the contacts a group called "not assigned". Instead of phone numbers I have email addresses in there.

I've tried to delete them but unfortunately without success!

Can you help me to delete the "not assigned" once?

Love
Chruseli

If the "group" field was the problem, surely you could assign them to a group.

These are your contacts?
