Movie Scene Capture (legacy) Burn-in frames in timecode not running

I’m using UE 5.3.2 for previz and render. I need to use the burn-ins that show several information needed in every single frame. One of this data is the Timecode, as it goes {hh}:{mm}:{ss}:{ff}. Well, seconds work perfectly (as I haven’t any shot longer than seconds), but frames are not running, it stays with zeros like: 00:00:12:00.
Surely something’s broken but have no idea where to look for. Does any one have any idea?
It’s the same with: {SourceTimecode} {ShotFrame}, frames keep in zero

did you ever figure this out?
