Resolve 20ß3 Audio rendered out of synch

I am currently running Resolve ß3. I have a short clip (ca. 38 sec) that I recorded on my Lumix TZ-95 camera. In the recorded file and in Resolve the audio is synched with the video. However, when I render this in the Deliver page, the audio, in the output file, is out of synch by half a second (timeline is 24 fps) . I've tried using the H.264 Master and the YouTube presets, both give the same result.
The first clip that I rendered was a shortened clip. I have since rendered the whole clip in isolation and still get the half second lag.
I can resynch the audio with the video by nudging the audio 12 frames to the right.
Original output was to MP4, further tests with MOV and MKV produced the same out-of-synch result
