Time Remap script for markers not working on certain comps

Hi there.

I have this script saved as an animation preset. This one works perfectly on certain compositions, but not all.

What I did was selected the time remap add a keyframe, paste the script. Save the preset.

As mentioned on most compositions it works, on others it doesnt.
When it doesn't i have to manually enable time remap and paste the exact same script. Then it works.
Feels odd, and I do not know what I am doing wrong here.

var numMarkers = thisComp.marker.numKeys;
var finalValue = value; // Default value if no markers are found

if (numMarkers >= 2) {
    var markerInTime = null;
    var markerOutTime = null;

    // Find the first "IN" and "OUT" markers
    for (var i = 1; i <= numMarkers; i++) {
        var markerComment = thisComp.marker.key(i).comment;
        var markerTime = thisComp.marker.key(i).time;

        if (markerComment == "IN" && markerInTime == null) {
            markerInTime = markerTime;
        } else if (markerComment == "OUT" && markerOutTime == null) {
            markerOutTime = markerTime;
        }

        if (markerInTime != null && markerOutTime != null) {
            break; // Stop once both are found
        }
    }

    // Ensure both markers exist
    if (markerInTime != null && markerOutTime != null) {
        var animationDuration = markerOutTime - markerInTime;
        var relativeTime = time - markerInTime;

        // Apply time-based transformation within the marker range
        if (time >= markerInTime && time <= markerOutTime) {
            finalValue = thisProperty.valueAtTime(markerInTime + relativeTime);
        } else if (time > markerOutTime) {
            finalValue = thisProperty.valueAtTime(markerOutTime); // Hold at OUT value
        }
    }
}

finalValue;
