Media Encoder CC 2019 won't pick up source fps when converting to ProRes 422 HQ

I have a large batch of .R3D footage from my Red Scarlet - W that I need to convert over to ProRes 422 HQ. Media Encoder isn't reading the source fps in the .R3D file. I click the Match Source button in the Basic Video Settings but it always coverts them to 23.976 even though some are 59.94. I have to go in manually look up the frame rate and manually set them in Media Encoder Frame Rate drop down.
