Why does my messaging app suggest I use John in all the address records?

Enter recipients in new message

Hi,

When I start to compose a new message and start to enter recipient typing the first letters (for example "john") the messaging application suggests all the address records containing "john" but the first suggestion line is letters combined with numbers - in that case "john" and "5646". What is that meant for and how do I remove it?

Thanks,

Jurgis
