MMU2 Purge Block Disappears with smaller Parts In Prusa Slicer

So This is wierd.  Using 2.5.0.  2 Filament Part. i3 MK3 MMU2 

If I slice the item at a larger size it shows the purge block and the 2 parts as separate filaments (correct). 

If I load in the same part but a smaller version (Or Scale down the original part in Prusa Slicer) Everything looks correct until you click "Slice Now"... Then the pruge block disappears and it prints it as a one filament part... 

Any Help would be appreciated.

Thanks

I am thinking this must be a problem with my model... I removed one the parts that was a different filament and it sliced correctly. Standby.

Wellp. Not the part.  It slices fine full size.  When I shrink (scale) to 80% - Slices Fine... Scale below 80% and the purge block disappears.

I re-created another part and tried a small part.  Seems there is a bug somewhere where small parts that are MMU2 parts wont slice in 2.5.0.

I have been using this MMU2 printer for years printing small MMU parts... This is the first time I have seen an issue like this.

SOLVED

Wellp - It was the part - Problem Solved.  One of the parts is modeled at .2mm, but somehow its importing as .1mm...  Re-Modeled at .4mm to be safe and everything works fine.
