Won't start because of Mojave, even when I am not on it

Just updated to the latest total finder version and it won’t start, because it keeps telling me that 10.14 has hardened security. But I am not even on 10.14, I am on 10.13.6!

Please install version 1.11.1. There was a bug with OS detection in that previous version. Sorry for that.

thank you!!
