exec node commands not being killed after payload is passed into it from discord get-msg node

I'm having an issue right now where when the msg.payload is passed from the get-msg node into an exec node it will run, but the pid won't go away and won't allow it to run anything other commands coming from the switch I have attached to the exec nodes. I tried setting a timeout on the exec node and it worked for the inject node but not the discord node. The weird thing is that it will work for a normal inject node with the exact same payload, but not with the discord get-msg node. I tried setting a timeout on the exec node and it worked for the inject node but not the discord node. I've been caught on this for a while and I don't know what to do next:( I appreciate any help
