That happened to me before. One time my avatar was Numbuh Three (from knd), holding a Rainbow Monkey on a turquoise background. And it took a few days for the new one to show.

After the new one started showing; that didn't happen to me again. Anyway, I just change my avatar like normally do.

So there for, it's a simple wikia difficulty or delay. It really isn't a big deal. Hope my advice helped you! ;)
