• Bug: the flat dictionary

I would like to give some feedback about ... When I solve the flat dictionary, it says task solved in the banner pic but below is written: ' "The Flat Dictionary" task doesn't accept solutions '

It seems to have accepted my solution and shows I have cleared the problem but I can't view any other solutions. Has it never accepted any solutions or something?
