Hi @Rolo Tomasi,
Are you using the V3? what version of Logic & macOS are you running?
Sorry but it seems we did not receive you email.
Anyways given the situation if the default theme is not correct, you need to do a force restore from the top bar menu Help > force restore logic resources.
You will need an internet connection.
This will fix it, but we would be interested to know what system you are running to see if this is an incompatibility or a bug issue type.
Thank you @oscwilde for pinging me.
