Issue with Leads Not Applying Spintax in SL: Seeking Feedback

Hey all we have this issue where leads pushing to SL (and not pushing any custom variables or copy) are appearing in SL but with no spintax being applied. In final review you'll see different variants, but none of them are actually spinning. (All the A's are the same, all the B's are the same etc) Curious if anyone else is seeing this?
