For some reason some of my contacts that I have saved appear just as phone numbers. I don't know why, but when I try to save them they have a wrong prefix number (+359, even though I am not from Bulgaria and none of those people either). Sometimes it is glitchy, ie. when somebody sends me a photo a group gets creates with me, my number and the sender. I don't know why this is happening. It has gotten less glitchy woth February, but some issues persist.
