in the sandbox setting the last three properties all have the same translation. Below is a simple fix for this.
i also renamed some of the others so they are inline with what Devs have named them in the map editors.

file:DWF\media\lua\shared\Translate\EN\Sandbox_EN.txt

Sandbox_EN = {
Sandbox_DWF = "Destroyable World Fences",

Sandbox_DWF_HealthHighWoodenFancyWall = "Health of Wooden Fancy Walls",
Sandbox_DWF_HealthHighWoodenFancyWall_tooltip = "",

Sandbox_DWF_HealthHighMetallicBarbedFence = "Health of military fencing",
Sandbox_DWF_HealthHighMetallicBarbedFence_tooltip = "",

Sandbox_DWF_HealthHighMetallicFence = "Health of High chainlink fences",
Sandbox_DWF_HealthHighMetallicFence_tooltip = "",

Sandbox_DWF_HealthHighMetallicFancyFence = "Health of black metal fancy fences",
Sandbox_DWF_HealthHighMetallicFancyFence_tooltip = "",

Sandbox_DWF_HealthHighWoodenWall = "Health of High Wodden straight walls",
Sandbox_DWF_HealthHighWoodenWall = "",

Sandbox_DWF_HealthHighMetallicMilitaryFence = "Health of portable fencing",
Sandbox_DWF_HealthHighMetallicMilitaryFence_tooltip = "",

Sandbox_DWF_HealthHighMetallicMilitaryBarbedFence = "Health of portable barbed fencing",
Sandbox_DWF_HealthHighMetallicMilitaryBarbedFence_tooltip = "",
}
