This module, and its buddies (uQMCV, uMCCGT,u16MCV), are 5HP in width, NOT 6HP as the original submission stated. Whenever this is inaccuracy is addressed by use of the 'Module Edit' facility, the algorithm to implement the width change seemingly fails, resulting in a severely screwed-up module image.
Anyone using MG to plan a future case should be aware of this discrepancy.
