I've worked through the same dilemma. I don't fully understand the details to give a good explanation but I think part of the problem is the labeling of the settings leads to bad assumptions about what they do. My hints based on experience but as I said less than full understanding, in order of what to try.
1. Set New and All Re-Triggers to new triggers only.
If that doesn't fix it, try one of these:
1. Sync the camera triggers and/or alerts to another camera that's working for you and has suitable settings.
2. Delete and re-add the camera.
If none of these things work, you're problem is harder to solve than mine was!
