Problem with deinterlacing (TFF and BFF in source change)

I'm trying to process video of hockey game.
Video is interlaced, so I do deinterlace with Yadif(order = 1, mode = 1)
to make double frame rate 59.94fps
The problem is that some parts of video are Top Field First and looks like some parts are Bottom FF).
Yadif(order = 1, mode = 1) - some smooth, other jerky
Yadif(order = 0, mode = 1) - other smooth, previous one jerky

Example:

around 15 seconds in, there's a change from TTF to BFF
It happens in many parts of video
Is there a way to solve this problem?

My script:

Code:

f1="WJC Rus-Swe.mkv"
video = DSS2(f1,FPS=29.97)
audio = DirectShowSource(f1,fps=29.97,audio=true)
AudioDub(video, audio)

yadif(order = 1, mode = 1)
lanczosresize(1280,720)
sharpen(0.2)
