In your mission with 3 POIs:
-Photo Capture Interval = 2 seconds.
The camera/SD card combination is NOT able to take photos that quick, Enter at least 5sec.
In your mission with 2 POIs:
-Photo Capture Interval = 11.5 feet
-Cruising speed = 22.1 mph (= 116,160 feet/h = 32.3 feet/s)
This results in 1 photo every 0.35 seconds !!
In your first post you wrote “I got to take a picture at way points” and in a later post “I really need the pictures in the same spot”.
Using the Interval feature is NOT the way to do this, you should turn Interval Off and add a “Take Photo” action at each waypoint to accomplish this and set “Path Mode” to “Straight Lines”.
Here’s a link to your mission with 3 POIs how it should be:
Also I bet that with both missions you got at least 1 photo taken.
