Gigs in some categories (such as SEO service, translation, etc) get a different interface. It's completely intended by Fiverr and is not a bug. Also, there is no way to switch between layouts/interfaces, so there is nothing you can do about this.
You can read more about the official announcement here:
If it's uploaded under a CC license, you can use it regardless of who is inside the video. Just make sure that the video is uploaded on a genuine platform by a genuine creator. You may get into trouble for someone else's actions, so it's important to check things in detail.
For example, if I download a video from YouTube and upload it on Vimeo with a CC license (even though it doesn’t really have a CC license), so you may get into trouble for trusting me. There are a lot of creators who steal others content and upload it as their own with random licenses. So, make sure to use content only from trusted sources.
