Weapons will not despawn properly?

After vigorous testing on one of my forge maps I can’t seem to get most of the weapons to despawn.

The weapons are set to despawn after 1 second of being abandoned/disturbed and they respawn 1 second after being disturbed. The only problem is they don’t despawn when left on the ground but still respawn after that 1 second. Their physics are set to phased. There is no spawning order set to any object and no scripting preferences.

Map object details:

FX: 96% goes up to 110% when all FX is activated
Objects: 1437/1600
Scripts: 273/512
Physics: 90%
Collision: 35%

Any help on getting the weapons to despawn is very much appreciated.
