Live edit for x3 not working?

Uploading my images, everything appears fine. Clicking "Apply All Accounts" and "Set Default for New Accounts" but still seeing unchanged version in end user panel.
Also I have only one style enabled, but users still can select all of them.
How can I change the images? And how can I restrict styles to chose from?

Edit:
Also tried this:
Downloaded the the (Yours) version of the style after editing, and uploaded it. But still no chance.

2nd Edit:
Changes are working for newly created accounts, but I cannot apply them to existing accounts.


Thanks.
