Mini Monitor / Mini Recorder interlacing error

Hey all,
I’m having an error with my Mini Monitor causing interlacing, and need advice on how to mitigate or fix it.

Here’s the basic workflow:
Sony PXW-X70 Cameras outputting 1080i60 > ATEM
ProPresenter outputting 1080i59.94 > Mini Monitor (SDI) > ATEM
ATEM > Multiview
ATEM > SDI-HDMI converter > Aux displays
ATEM > Mini Recorder > Wirecast

The ATEM is set to 1080i59.94. I have no interlacing on the multiview or TVs, and no interlacing on the cameras. The only way I get interlacing is the Mini Recorder > ATEM > Mini Monitor, there’s no interlacing at any other point on the chain.
I’m guessing it’s a field order issue, and if anyone has ideas I’d appreciate it.

Wirecast doesn’t do de-interlacing, so I’ve had to roll back to OBS until this is solved.

Update/solution

The error appears to be in ProPresenter specifically. When the video is output through BlackSyphon there is no interlacing present. A ticket has been submitted to Renewed Vision over it.
