I’m not sure if it’s every language(This is Japanese), but recently I when I try to order the searched lessons by Percent of number of new words it does nothing. Also the Show/Hide spaces button does not work in lessons anymore. Just giving the heads up.
Two bugs that have been duly noted. It looks like the first one is an issue with the “calculate” button not working, but nonetheless we’ll get it figured out.
Thank you very much for the heads up
