So, here's part of my program. At the moment the problem I'm experiencing is that if I choose the contact that is stored LAST (ONLY THE LAST ONE) and update its details, the program, instead of overwriting it, puts the modified data as a separate block BEFORE the last contact. For example,
I have the contacts
Abc
Def
Ghi
I can edit Abc and Def just fine... but if I choose Ghi, and say replace the details with Name as Xyz, this is what I get
