Inserting a block

Whenever i insert a block on my laptop it doesnt show a preview or when the block has attributes and i insert it, the edit attributes meau doesnt pop up like it should. I know that the block is made correctly becuase when i open the same file on another computer and insert the block with attributes the edit attributes menu does pop up. Can anyone tell me why it doesnt pop up on my laptop? Thanks
