Maintaining Email Structure When Integrating Twain and Lemlist

Hi, quick question about the twain and lemlist integration. When I set up everything in Clay it works perfectly and the mails are well structured. However, once I push the leads directly from Clay into my lemlist campaigns, the mails are loosing their structure (see screenshots - status quo & how it should be). Does anyone now how to push leads directly into campaigns and maintain mail structure? Otherwise a lot of manual effort to correct...
