VI select visual block cannot reach the end of line

Question

I was trying to select a block of code and do the word replacement inside that block.

(Trying to replace all the letter b in the second and third line with letter d)

However, I cannot reach the end of a few lines while selecting.

For example, I cannot select all the characters in the second and third line. Any idea how can I do it? Images below shows how much I can select at most for the second and third line, cannot move the cursor further to the right.

Thanks!
