How to remove unused english letters from column in right side of contacts program?

All names of my contacts starts with cyrillic letters, so contacts wants to show two alphabets - russian and english, and it's not possible to use it at all.

I found solution in cydia some years ago - "ABFIX", but i don't want now to jailbreak my iPhone to use this program.

Another solution is to use different program for calling people, like Slide contacts, but i prefer native solutions.

If it is possible to contact someone in apple developers comunity to ask them to remove this VERY-VERY old bug?
