Problem With Journeys and Lead Page

Hi, I contacted support at zohomarketingautomation.com about an issue last week, but have yet to have a response.

I have built a critical journey for our customers, but they are skipping the email, at least that's what ti looks like (there's no explanation). Furthermore if I try and click through to one of the customers, that page won't open.

Please find the screenshots attached.

Any help with what is happening here?

Thanks

Dave
