[Question about rich media]

Hello, we faced a problem.

Zone - Rich-Media and HTML banners
Banner - 800h500px,

When no restrictions are chosen
Delivery capping per visitor "-" - the number of impressions and unique visitors is approximately the same.

If we set restrictions in the parameters of a banner or a zone, or in both of them, for example:

Delivery capping per visitor
Limit banner views to:
 in total 1

OR

Limit banner views to: -
per session 1
Reset view counters after: 24 hours

OR

Limit banner views to:
per session 1
Reset view counters after: -

then the number of unique visitors becomes COMPLETELY different compared to impressions;
a very large number of impressions is marked as «impression blank» in the statistics of a particular site, e.g.:

the number of unique visitors is 10,000 a day,
the number of banner impressions in the statistics – 500, impression blank 9,500.

The unique calling code (Zone ID) is placed on 20 websites, and Rich Media (Fullscreen) is already bound to it. On 1 site or 2 or 5 or 20 sites - all to most.

What is the problem? Why do such large losses in impressions take place?

Where can we edit or add-on our styles for Rich Media design, for example, change the appearance of “x” to close the window, make banner background semitransparent?
Is it possible to close a banner window by clicking on background or pressing ESC instead of pressing “x”?
