I need help with railroad crossings

[HybridGrizzlyTrenchGun]

I've been using the TRC system for some times now, and it was really amazing, but now for some reason the TRC scenery (rail crossings without a track or road spline connected with them that you have to position yourself), malfunctions every time a train goes by.
As the train comes, the crossings activate, but instead of just having the gates go down like normal and stay active until the train passes by, the gates go up and down continuously and the bell rings rapidly.
I have one TRC 3 Trigger for closure of rail on both ends.
Both TRC arrows have the X&X (e.g. 11&4) name and are set to 50m for front and rear radius, the option to stay open is selected as "yes" with both directions being covered and they are connected to both TRC US M Scenery rail crossings.
I have the Road 2l 01 running across the crossing tracks with JR Concrete Grade Crossing covers on the tracks.
Traffic runs through the crossing, but I don't have a TRC traffic stopper that supports one track (they only stupidly come in two tracks and above)
There are additional Grade Xings behind it.
The Multi Ind str l= 60m EN runs halfway across the crossing.
I also have ATLS TRS19 triggers set up to Channel 1, SPL/LCM, and responds to all Train Priorities 1,2, and 3.
There's one on each side of the crossing
There's one ATLS CONTROLLER TRS19 set to channel 1, with level crossing mode selected, and no phases currently set.

So what am I doing wrong? How is this happening? Is there any way to fix it? How do I avoid this problem in the future?

Same problem for me, no way to fix it, use another type.
