I noticed on the Trigger tool in the Detection tab, when I run a single railcar over it, it performs fine, but when I have multiple cars hooked together, the tool still recognizes a prop even though nothing is there.

I have provided some screenshots to help explain what's wrong:

This is what it shows when nothing has passed it. Notice the 0 on the value screen in the background: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=506087561

This is when 1 railcar passes the trigger. The screen shows a 1 indicating that it is detecting one prop: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=506087579

When that one railcar passes, the value turns back to 0 like it should.

When I have multiple railcars hooked up, the value will change to 1, then to 2 when detecting both railcars, then back to 1:

Finally when they pass, rather than the value returning to 0, it sits at 1: http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=506087620

When I moved the railcars pass the trigger again, the value increases to 2 once they pass.

A fix would be nice as I am using this tool to activate/deactivate a railroad crossing and this bug is preventing it from deactivating. Thank you.
