Great thanks @ruanyl, I just found one warning message for this PR code on my local console when I input boolean value on my local.

reproduce:

Warning: Failed prop type: Invalid prop `value` supplied to `EuiSelect`, expected one of type [string, number].
    in EuiSelect (created by ValueInputTypeUI)
    in ValueInputTypeUI (created by InjectIntl(ValueInputTypeUI))
    in InjectIntl(ValueInputTypeUI) (created by PhraseValueInputUI)
    ......

@junqiu-lei nice catch on the EuiSelect warning! But it looks like it's Eui related, it actually happen to EuiSelect component on other places as well, like on Discover page, when you add the same filter, you could see the same warning(to see the warning, try to refresh the page and start from scratch).
