I think I've seen that issue before. Basically, when Daisy gets a new outfit, the game is assigning her portrait and body by loading directly from the original game assets instead of using the image constants that were set up previously.
You ought to be able to work around it by going into her portrait customization settings and manually selecting one of her unique sprites. This will replace the defaults that the game set up.
Due to a bug in the game, though, I think the regular maid outfit will be missing. :(
