Exception when turning on OCP guidlines

[FrancescaWatson]

For User defined Active material, If I switch on OCP guidelines in "Fill in 'Active Material' parameters" I get the following exception. It is the same for both negative and positive electrodes.

`StreamlitAPIException: get() is not a valid Streamlit command.
