Styles conflict in inventor

How can I stop styles conflicts in Inventor? I followed a tutorial and saved my new standard within the template document but I still get the conflict message. The message says there is an option in the files tab of application options to set Use Style Library = no but can't find such a thing. I'm using Inventor LT 2019.

Thanks for the assist guys. Looks like the problem was that I had somehow overwritten the default standard/style. Managed to get a clean copy of the styles library and then created a new standard within the default standard. Ok now.
