I'm pretty sure whoever was writing the filler bits with Macao and Wakaba simply forgot that Macao already knew transformation magic (hell, he's probably the one that taught it to Mirajane when you think about it). I can't fault them too much for it. It's never been a big magic of his, was last used over 200 episodes ago, Shinji Ishihira is currently handling both Log Horizon and Fairy Tail and is probably swamped with work, and Mashima's pretty much managed to get himself swamped with work as well. Not that difficult for a detail like that to slip through the cracks on a comedy based episode.
