Scripts Not Working

I installed a few scripts and also ensured scripthookv and scripthookvdotnet were up to date. I have the roll off bed script and the vehicle trailer script installed. The issues I am having is 1: The flatbed roll off mod where you can lower and raise the bed The white marker does not show and I cannot use the script in game. 2: The car trailer mod where you can lower and raise the back racks and load a car and secure it does not work. Same issues where the marker does not show and I cannot use the script. Usually ther eis a message on the top left that shows what key to press. Any help would be greatly appreciated. I also attached my gta 5 file directory. Thank you!
