Unplayed episodes

Hi! I recently abandoned Pocket Casts. I'm quite happy with Podcast Republic, but I'm having a problem with the filters. I want a list of episodes that haven't been played yet. To achieve this, I created a filter with the 'playing state' set to 'unplayed' (less than 99% played). However, when I play an episode from this list, it stays on the list even if the playing progress is far below 99%. I don't want that. Once the playback progress is below 99%, it must disappear from the 'Unplayed' list. Please sort it out, thanks.
