Color mattes offline during export in projects imported from Premiere CC2022 to CC2023

Macbook Pro M1 Max, Ventura 13.1

Premiere 23.1.0

Opened a project created in CC2022 inside Premiere CC2023.  When exporting through Media Encoder, I get a warning that "Color Matte" is offline.  It's online in Premiere- everything looks fine- but then has a red offline image in the exported file.  I tried making new color mattes inside CC2023 and replacing the existing ones throughout- didn't work.  I tried creating a new project in CC2023, importing the previous project- didn't work.  Tried clearing the Media Cache- didn't work.
