As the row label and text field have different and consistent formats (bold/colour), it can be implicitly seen that a given label applies to a given field/option so there's no real need to use a colon at the end.
By removing the colon from the string, we can also use them for titles etc without it looking strange
Whilst most labels previously had colons, many were missing which can give the UI a confusing look
