I cannot figure out why I'm getting the weird border appearance that I'm getting in my newsletter draft. The image below shows the view I get in my MyEmma layout screen (1). All good there -- and the "preview" screen looks the same way. But when I send it to myself, I get the weird appearance shown in (2, see red circles) where my button elements have fine-line borders above and below them, and the right-side vertical border line disappears. very frustrating... any idea what's going on? This all seems to have just suddenly started after working fine for quite a while... Thanks.
