Connection Variables glitch when there are multiple connections

[DrprofLuigi]

In the following screenshots, the trailer stand has the following animation:

			{
				"objectName": "$Stand",
				"animations": [
					{
						"animationType": "translation",
						"variable": "!connection_1_1_connected",
						"axis": [0, -0.375, 0]
					}
				]
			}

There is an invisiwheel that applies after this part to hold the trailer when no truck is connected.

When the trailer is by itself, everything works as it should:

However, when there is a dolly connected to the bumper part on the trailer, the variable connection_1_1_connected seems to get confused and not work properly:

I believe this is because somehow connection_1_1_connected is pulling from the bumper part, rather than the trailer:
