Quest \"Workshop Ivaldi\" - gathered enough dust, but the dwarf the key doesn't (God of War (2018))

The first time when went to Niflheim, I did not notice this line of quests and went into the maze. Gaining about 1K dust, returning back to the dwarf and he gives the job to recruit 500 dust on the enter key. After that, whatever I do, I key it does not (no interaction via the triangle), but each time says I have typed enough. Save no what to do?
