Weird timecode format when exporting subclips

Hello,

I am having a weird problem when transcoding subclips from Prelude. When I ingest the footage back in Premiere, the timecode of the footage is all messed up and displays a 3 or 4 digit number (ex: 3311 or 477.. etc) instead of the actual duration in a timecode format (00:00:00:00). The original clips are displaying fine in Prelude before transcoding. I don't know what the issue may be since I haven't seen this before. Is it maybe an export preference, or is it a bug?

I also tried to export a clip straight from Media Encoder using the same settings and when imported back in Premiere, the timecode is as expected, looking at the bottom clip in the image (GOPR0631). Also when importing the transcoded clip from Prelude two other subclip files come with it, which obviously I don't want, since I already pre-selected in Prelude and I just want all the subclips I defined treated as individual new files. 

Any input is highly appreciated!
