Convert profiles cannot be reset to default settings.

I was converting videos and needed to change the resolution width.

Used the "Video - H.264 + MP3 (MP4)" profile and under Video codec tab and Resolution tab, I changed the Frame size Width from "Auto" to the required size and completed my process.

I went back in to change the Frame size back to "Auto" and the field only accepts numeric input.

I deleted the Profile and created a new one, which solves that issue. However the new Profile under the Video codec tab and Encoding parameters tab the Bitrate was set as "Not Listed" and with a new profile its default setting is 800 kb/s. This cannot be set to "Not Listed" as it only accepts numeric input.

I can see the reasons for the numeric input only, so maybe a "Reset to Defaults" button for the profiles would work?
