K M spark doesn't work in 117009


Subways and railroads
I have the "K M Spark" "KUID2:571870:2070:3" I've used it in previous 2019 patches and it works fine, but I noticed in my current patch 117009 it doesn't flash in driver mode when the bogey passes it, instead in driver and suveyor mode it just stays lit. I wanted to reach out to the creator/author, but I don't think he's active in trainz anymore. how can I fix this?
