I would recommend the following. Discard current oring. Clean any trace of lubricant from the channel. Install new oring.
In my experience a din oring popping off the first stage means that I didn't completely depressurized the regulator. Try depressing the purge for 15 seconds after the sound stops.
Hopefully this helps. Let us know.
