Funny thing, the Transpose +/- 12 are working this morning without having to first select notes. 
Delete Note by length is still problematic.
I generally set the Function for Select, then Apply to see how the LE responds if I have any concerns.
Delete Short Notes selects nothing.
Delete notes Bigger or Equal selects all notes no matter what the parameter value is set to. Fer’ instance, if the parameter is set to note length bigger or equal to a note 3 beats in length, the LE will also select sixteenth notes and notes that are measured only in ticks.
Sometimes, the notes disappear from the Key and List editors when attempting to select notes in the LE.
Not to be a wise#@$!!, but it looks like the LE sometimes (but not always) deletes the notes when the Function is set to Select.
