I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in a clean project?
  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?
  3. Could you provide screen shots of any blueprints/widgets that may be involved with this issue?

Hi Rudy,
I’m not being able to replicate it on a clean project, and it is too time consuming at the moment to try further. If with any luck I’ll be able to pinpoint the problem, I’ll post it.
