Forward and Rewind on MKV playing from USB

I have an issue when playing remux mkv’s from my external HD via USB. when i want to forward or rewind more than 2x speed the search bar shows the film forwarding but when i hit the play button to resume, the film will resume from where i initially wanted to forward from ! is there a way to resolve this issue. I remember having the same issue on my Vero 4k when playing movies.
