Bug description

My english is not good but here we go.

When I create a board and then configure it with the people I want to access it, with the people I'll share it with, everything works perfectly, but when I makes a mistake and wants to delete someone they don't need on the board, or if time passes and you want to delete a member who's being shared with you, you can't; you have to delete the entire board and recreate it, cause the delete shared item dont works

All of this happens in Deck.

Steps to reproduce

i go to a board in the three pints "..."
clic on details of board
in SHARE, i try to delete a user and there is...

notting happens

Expected behavior

i expected to get it a user deleted from the list of shared from my board created
