Um having problems with the rewinding of the app

When I pause the audiobook instead of rewinding 2 seconds when press play it skips parte of the audiobook, I tried putting more seconds on the auto rewinding settings but then it rewinds a lot more then it should, if I put 20 second rewind it rewinds two minutes for example. I used to use this app and had no problems on my old phone, but this new version seam's to have this bug.
