So the whole specifying a version is new to me, but here's how to do it for the uninitiated. Based on github thread, I'm dropping back to tag 83 (from: https://hub.docker.com/r/linuxserver/jackett/tags/) In the edit screen of the Jackett docker, turn on the advanced view (top right). In the repository field add a colon + tag number so it looks like: linuxserver/jackett:83   This fixed the issues I was having.
