This discussion would be more helpful on the specific comic's talk page, but that's just a request for next time.

I looked into what you were talking about. It seems the only character that appeared that was dead at the time of this issue was Bootface, who, as you mentioned, was killed by Two-Face during Forever Evil. Honestly, his appearance was probably just a mistake behind the scenes rather than some complicated timeline puzzle. Robin Rises, the event preceding this issue, no doubt takes place after Forever Evil, with the whole Batman Eternal year in between the two.
