this is the same MG preset and it seems there is no problem in RC v3.1b16 (x64) even without editing the phrase length.

both request sounds good to me..
about the Resizing ..
you are modifying original length of phrase,
after drag phrase first time, select the Resize Mode: Repeat / Scale ... and change the "Resized Length:" only...
changing original length needs to be re load same phrase to restore to the original size as i know.
let me know if miss something!
