How To Correct Logcat Missing Filter In Android Studio

Before trying to restart the Android Studio in order to make the logcat filter fields re-appear (this did not worked for me the last time), simply try first to change the window size to “Restore Down” and back to “Maximize” or the other way around. (This worked for me on Windows 10).

Here is what I mean:

"Restore Down"

"Maximize"

I hope this helps.
