playback position not remembered

Describe the bug

A clear and concise description of what the bug is. i am trying to use otter and funkwhale to play audiobooks which is working but last played position is not being remembered. How to reproduce

1. Go to 'album which is an audiobook
2. Click on play at the top (i have set otter to play in order/not shuffle)
3. reach a certain position,
4. pause.
5. press the play button at the top to play again
6. the book starts from the start

Expected behavior the play/pause button should honor position same as the button at the bottom this happens when you switch to another album and press play again.
