@homerchen19 Thanks for reporting this - I thought it may be because you set both defaultValue and value in your screenshot, but I can reproduce it with an out of range value (no defaultValue)

Just for comparison: clickaway works correctly with an out of range value in Material UI's Select (demo)

<Select value="abc" label="Age">
  <MenuItem value={10}>Ten</MenuItem>
  <MenuItem value={20}>Twenty</MenuItem>
</Select>

JFYI, I noticed this bug after installing version "5.0.0-beta.29" which contains this PR
