Question the relations between 'Image thumbnail' and 'I-frame interval'

Hi, 

I am testing HLS - image thumbnail on Rokustick 4k device.

However, I cannot solve the following problem.

 

Video 1080p@29.97, for video with segment duration 2sec,  with Jpg image Thumbnail

Dash and HLS manifest were created for the same video, 

When I select a HLS video thumbnail on Rokustick, the video is played from the previous segment rather than from the exact position.

Dash is played from the exact position corresponding to the thumbnail, while HLS is played not from the exact position, but from the video of the previous Segment.

The syntax of Dash and HLS is as follows.

What's the problem with m3u8 files in HLS?
