Showcase Bug (Empties all and can't add more than one)

Bug Effect: After the maintenance I tried to replace a Pokemon in the showcase. Instead of removing one, the entire showcase was emptied. Upon trying to add them in again, I was able to place one Pokemon in, but as soon as I place a second in, the first gets removed. I'm currently only able to have one Pokemon at a time in the showcase. What you were doing when the bug occurred: I clicked the X to remove a Pokemon. Then, after the entire Showcase got emptied, I clicked an empty spot in the showcase and selected a Pokemon, twice, on the second time the first Pokemon got removed.
