Odd Doubling of (Flash?) Adverts in webarchives?

Hi all-

Curious if anyone else sees this. The image below shows a webarchive I made displayed in the DTPO browser (left), and alongside (right) “Opened In…” Safari. As you can see, the adverts are doubled (tripled?) up. I get this quite a lot for certain sites and wonder what’s up.

Best, Charles
