ImageClassifierCleaner is not working correctly

In the ImageClassifierCleaner(), if I change from cleaning one category (say black bears) to another (grizzly bears), the cleaner instance seems to lose all the changes you’d been flagging for black bears (i.e. the previous category). The same issue happens if change from the training to validation set under the same category.

This is happening with me as well, it ends up breaking the continuation.
