Changes to contact list columns not retained across version updates

I’m running eM Client V6.0.19762.0

Changes I’ve made to the column configuration in Contact Lists, are not retained across a version updates. I’m using the Phone List configuration.

As I use a number of different contact lists, this means a lot of re-applying thes changes.

Hi, I am sorry for long delay, but I was unable to reproduce this. Could you tell me exact steps where and what exactly is not working for you?
