LPS-43622 Changing the pop up layout on the export screen

Hey Chema,

We have been conding the new features for staging and @LeventeHudak has sent me a small change what changes the current pop up style layout. We won't have pop ups for the new features in staging.

I've checked the code, and it looks fine for me, but there are some CSS change, I think you could review better than me.

Thanks,

Máté
