Razer synapse - Macro problems

hello, I'm here to ask you for help because maybe I found a bug and I don't know how to go on I'll explain better; I was creating a macro for the auto-run on dayz the macro consists in pressing W + Shift and in the middle put a delay to make it run to infinity and up to here no problem, the problem appears when I go to insert the macro in the key ( I have a huntsman but a friend of mine has also tried who has a naga chroma and has the same problem) putting the macro with switch on / off, it starts but then does not stop the same for the third option that is that you have to hold down to do it working here too starts but then releasing does not stop and the only way to stop everything is to stop synapse and all its background processes. Below I leave you some screenshots regarding the macro itself. I hope you can help me because I have also done it with other programs from other houses (logitech, trust etc) and it has always worked but here it gives me problems. .
