DeckLink Mini Recorder Video not synced with audio

I have the DeckLink Mini Recorder installed in my Windows 10 PC. I am presenting to FB Live via the Live Presenter HD with the audio and video in sync. My local recording has the audio leading the video by about 2 seconds.

Where should I change an option to get the audio and video in sync on my recording? If you can't tell, I am a novice so keep it simple, please.

Not sure if this will help but the manual mentions, ‘playback > video device > offset’ setting.

Johnathan, thanks for the suggestion. I adjusted those values up and down without any effect.

Upon further testing, instead of just viewing the recording via Live Presenter, I just played back the produced video with Media Player and the video and audio were in synch. I don't know why the playback thru Live Presenter is out of synch but playing back thru Media Player is in synch.

That being said, I don't have a problem. Thanks for your suggestions though.
