Android 10 Swipe Forward
It is not a bug. Swiping to move forward as not yet been implemented natively only swiping to move back


  with the new system navigation mode - users can navigate back (left/right edge swipe), to the home screen (swipe up from the bottom), and trigger the device assistant (swipe in from the bottom corners) with gestures rather than buttons.


To use the swipe forward gesture, the app should implement it (ie Chrome).
