Visual block edit in vim

Question

I have refer to this post to use block editing in vim. But when I key I or c after the block select, vim enters the normal edit mode just as if I pressed a i. I also found, when block is selected, I can use the x key to delete chars in the block.

Before press I:

After press I:

How can I block input chars?

the +visualextra have enabled from below version info.

After pressing I in visual block mode, vim appears to have entered insert mode. But when you exit the insert mode and go to normal mode again, you will see that the keys you pressed in insert mode have taken effect in the entire selected block.
