Major color bleed on MMU sheep “mascot”

I just did my first few MMU prints. One print was Ewenice (well, that’s what I’m calling the sheep Prusa says is their mascot for multifilament printing - Ewe-nis, or Eunice). What I got is in the attachment. Note that on the layers where I used black and blue, even with a wipe tower, there was a lot of bleed

I’m using a Mk3.5 and downloaded the file directly from Printables, didn’t edit it or change anything (that I know of), and printed using Prusa Connect. Did I miss something? Or do I need to fix something on my printer to prevent this from happening?

RE:

For lighter color filaments following darker ones, I always increase the purge volumes when loading the lighter color filaments.  In the image this would be lane 5 for the oncoming yellow filament and I would probably start by increasing the default value from 80 to ~ 200 and give it a try.

Thank you! Since this was all pre-defined in the file for Prusa Slicer, I was concerned that it might be something I did wrong in the MMU setup, and not a setting issue.

This will take a few days before I can test it. (I spent so much time on the MMU that I have to focus on a few other things for the next few days.) I'll report on how it works.
