Auto completion suggests will not refresh when I paste

there is such a scene:
when I rewrite a history command like `grep 'xxx' xxx.log`, I delete the `'xxx` with ctrl + w.
Then I input a `'`, there will be a suggestion here from the history, and I paste a new key words like `yyy`, the command will be `grep 'yyy' xxx.log`. But the suggestion hasn't gone away, when I click the `return`, the suggestion will replace the command to `grep 'xxx' xxx.log' xxx.log`. This always bugs me when I type too fast.
