Hi, as the title says I'm stuck in artifact challenge step 6, I have a challenge that do not advance (6.7)

If I understood it correctly all I have to do is put 3 pices of equipment that have 3 or more stars to 3 diferent heroes no?

That should be it, but since nothing happened I searched in this forums to see if someone got the same problem before,

I found a moderator who recomended to remove the artifacts and equip them again with 0 enchants and so I did it

I equiped more heroes with 3* artifacts but again nothing happened.

Additional info

1 my ID is 680640

2 server is Production 1

3 Don't thing is important but I use BlueStacks 4 -> 4.31.56.2510

4 all heroes in te images wear the sets at the same time i did not switch it and take a picture.

5 when I got to step 6 the mission already was at 2/3 perhaps because I have 2 heroes with full 3* set

Thanks in advance, and keep the hard work, I enjoy playing this game.
